In this post we will try to learn how to diagnose and repair an inverter, by comprehensively learning the various stages of an inverter, and how a basic inverter functions. Before we discuss how to repair an inverter it would be important for you to first get fully informed regarding how does an inverter worka.
The following content walks you through both the aspects which can prove very useful to any electronic technician. Stages of an Inverter As the name suggests DC to AC inverter is an electronic device which is able to convert a DC potential normally derived from a lead-acid battery into a stepped-up AC potential which may be quite comparable to the voltage that is found in our domestic AC Mains outlets. Repairing sophisticated inverters are not easy due to their many involved complex stages and requires expertise in the field. Inverters which provide sine wave outputs or the ones which use PWM technology to generate modified sine wave can be difficult to diagnose and troubleshoot for the folks who are relatively new to electronics.

However, simpler inverter designs that involve basic operating principles can be repaired even by a person who is not specifically an expert with electronics. Before we move into the fault finding details it would be important to discuss how does an inverter work and the different stages normally an inverter may comprise: An inverter in its most basic form may be divided into three fundamental stages viz. Oscillator, driver and the transformer output stage. Oscillator: This stage is basically responsible for the generation of oscillating pulses either through an IC circuit or a transistorized circuit.
These oscillations are basically the productions of alternate battery positive and negative (ground) voltage peaks with a particular specified frequency (number of positive peaks per second.) Such oscillations are generally in the form of square pillars and are termed as square waves, and the inverters operating with such oscillators are called square wave inverters. The above generated square wave pulses though are too weak and can never be utilized to drive high current output transformers. Therefore these pulses are fed to the next amplifier stage for the required task. For info on Inverter oscillators you can also refer to the complete tutorial which explains how to design an Inverter from the scratch Booster or Amplifier (Driver): Here the received oscillating frequency is suitably amplified to high current levels using either power transistors or Mosfets.
Though the boosted response is an AC, but is still at the battery supply voltage level and therefore cannot be used to operate electrical appliances which work at higher voltage AC potentials. The amplified voltage is therefore finally applied to the output transformer secondary winding. Output Power Transformer: We all know how a transformer works; in AC/DC power supplies it is normally used to step-down the applied input mains AC to the lower specified AC levels through magnetic induction of its two windings.
In inverters a transformer is used for similar purpose but with just opposite orientation, i.e. Here the low level AC from the above discussed electronic stages is applied to the secondary windings resulting in an induced stepped up voltage across the primary winding of the transformer. This voltage is finally utilized for powering the various household electrical gadgets like lights, fans, mixers, soldering irons etc. 'You may also want to learn Basic Principle of Operation of an Inverter The above diagram shows the most fundamental design of an inverter, the working principle becomes the back bone for all conventional inverter designs, from the simplest to the most sophisticated ones. The functioning of the shown design may be understood from the following points: 1) The positive from the battery powers the oscillator IC (Vcc pin), and also the center tap of the transformer.
2) The oscillator IC when powered starts producing alternately switching Hi/lo pulses across its output pins PinA and PinB, at some given frequency rate, mostly at 50Hz, or 60Hz depending as per the country specs. 3) These pinouts can be seen connected with the relevant power devices #1, and #2, which could be mosfets or power BJTs. 3) At any instant when PinA is high, and PinB is low, the Power Device#1 is in the conducting mode, while Power Device#2 is held switched OFF. 4) This situation connects the upper tap of the transformer to ground via the power device#1, which in turn causes the battery positive to pass through upper half of the transformer, energizing this section of the transformer.
5) Identically, in the next instant when the pinB is high and PinA is low, the lower primary winding of the transformer becomes activated. 6) This cycle repeats continuously causing a push-pull high current conduction across the two halves of the transformer winding. 7) The above action within the transformer secondary causes an equivalent amount of voltage and current to switch across the secondary by means of magnetic induction, resulting in the production of the required 220V or the 120V AC across the secondary winding of the transformer, as indicated in the diagram. DC to AC Inverter, Repairing Tips In the above explanation a couple of things become very critical for obtaining correct results from an inverter. 1) First, the generation of the oscillations, due to which the power mosfets are triggered and the process of voltage induction is able to take place across the winding of the transformer. 2) The second important factor is the frequency of the oscillations, which is fixed as per the country’s specifications, for example countries that supply 230 V, generally have a working frequency of 50 Hz, in other countries where 120 V is specified mostly work at 60 Hz frequency.
3) Sophisticated electronic gadgets like TV sets, DVD players, computers etc. Are never recommended to be operated with square wave inverters. The sharp rise and fall of the square waves are just not suitable for such applications.
4) However there are ways through more complex electronic circuits for modifying the square waves so that they become more favorable with the above discussed electronic equipment. Inverters using further complex circuits are able to produce waveforms almost identical to the waveforms available at our domestic mains AC outlets. How to Repair an Inverter Once you get well versed with the different stages normally incorporated in an inverter unit as explained above, troubleshooting becomes relatively easy. The following tips will illustrate how to repair DC to AC inverter: Inverter is “Dead”: Check battery voltage and connection, check for a blown fuse. If that’s OK, open the inverter outer cover and do the following steps: 1) Locate the oscillator section; disconnect its output from its preceding stage and using a frequency meter confirm its proper working. No frequency or a stable DC indicates a possible fault with the stage. Check its IC and the associated components for the remedy.

2) In case you find the oscillator stage working fine, go for the next stage i.e. The current amplifier stage (power mosfet).
Check each device using a digital multimeter. Remember that you may have to completely remove the mosfet or the BJT from the board while testing them with your DMM.
If you find a particular device to be faulty, replace it with a new one, and check the response by switching ON the inverter. 3) Sometimes transformers also become the major cause for a malfunction. You can check for an open winding or a loose internal connection in the associated transformer. If you find it to be suspicious, immediately change it with a new one.
Although it won't be that easy to learn everything about how to repair DC to AC inverter from this chapter itself, but definitely things will start 'cooking' as you delve into the procedure through relentless practice, and some trial and error. Still have doubts.feel free to post your specific questions here. Please send your queries through Comments for quick replies!
Hello, I have a Go Power 1500 inverter and was using 4 - 6v AGM batteries to power the RV. The inverter when turned on goes into it's start up procedure and when finished it goes immediately into overload. I installed 4 new (same) batteries and it continues to do the same thing. I disconnected the inverter when the issue first happened and the batteries swelled and started smelling so I removed those too.
Is there a component inside the inverter that would make the inverter revert to overload even with brand new batteries and everything else is fine? No tripped GFCI, or inline fuses blown etc. I didn't open the cover and inspect for any burnt components yet and the inverter itself doesn't smell like a capacitor etc. Is there anywhere that repairs these as Go Power doesn't repair their units so, I was forced to buy another inverter! Thanks in advance. Hi, i have a 2500 watt 12volt/240volt inverter, on the same system i also have a generator which takes over when the batteries are low.
Sukam Inverter Circuit Diagram Manual
I have 2 rotatry switches operating the electric, however as expected i turn the generator power while the inverter power was also live thus putting 240 volt power to the 240 volt supply from the inverter. This tripped the breaker on the generator and although i have reset that the inverter now does not work. It has illuminations lights on it, it makes a pulsing noise and there is a slight smell of burning although the fan still works. What do you think? (not of me lol but of the inverter please)!! My issue with a ready-made inverter is not considered here. From the beginning, this inverter worked fine for charging, but always made capacitive-input devices behave erratically when plugged in.
The trackpad on the laptop doesn't move the pointer on the screen properly, and has a lot of jitter. Problem disappears when the device is unplugged from inverter. And perhaps more dangerously, a particular USB charger plugged in the 120V outlet (I know it's an inefficient use of the inverter;) gave me a discharge from touching the metal case of the tablet.
This charger doesn't have any issue when plugged in at home, even though the mains is ungrounded. Maybe it was the charger or simply static electricity build-up on me from repeatedly moving to and from the driver's seat. Still, how would I know what could be at fault in this case? I have no oscilloscope to verify the waveform or possible spikes, though I'll see if I can build a USB one. Selim, are you sure the inverter is generating the correct RMS voltage? You can confirm it by checking the output voltage with a multimeter set at AC 250V range.
If it shows over 150V, the high voltage could be causing the issues. Or it may be due to the high amount of harmonics from the inverter. Try adding a 0.22uF/400V capacitor right across the inverter output terminals and check the results. Inverters normally do not have a neutral, they have an alternating phases coming out of both their outputs pins, that's very unlike our mains AC, this could be the cause of the slight shock that you are getting from the charger body.
Hi, I used my 300W inverter (12Vdc to 230Vac) to power a double tube flourescent light fitting. The total wattage of the light fitting is 130W. The tubes lit up, but then after switching off the light fitting and then switching it back on, the inverter failed. There is a red LED indication on the inverter which means that there is a fault. What could I have blown? Could the high inrush current have blown some component, or could a switching surge have blown some component? What is the most likely component in the inverter that could fail due to the inductive load which I subjected it to?
Please reply soon, Riyaz. Hello sir howcr u. My problem is that i m having a luminous 800va inverter 150amp battery attached to it.it's charging led were not working.so when i was repairing that board.it touched in heat sink of mosfet.after that none of the led's are working.it's not a big issue but.main problem is that inverter giving low output voltage 150 volts.on load and on no load.i measured it's battery charging amperes.which is 12amps.i tried different battery but problem is same.are mosfet's blown up???
If yes how can i check them with multimeter.??? Hello sir.there are two series of 5-5 mosfets each in my inverter.so one mosfet was looking cracked.so i changed whole series of 5 which was chn 608 with chn 347.when i connected battery it was working.but whenever i put load on it.,it started switching power on off immediately.and its relay started making noise.i remove load.after few minutes.a mosfet fried again with a pop sound.and a little transistor 639 started smoking.can u determine what's the exactly problem??? Wish u a happy diwali. Hi, I compared the pinouts of your inverter IC with a more commonly available IC TL494 and they looked exactly similar. So I think you can try replacing the burned SDC7500 with a TL494 and check the response.
However I can be difficult to understand or judge the actual reason behind this damage, because normally the supply to the electronic stage is always regulated and through a step down transformer. I have a simple inverter version which is comparable to the one that you are using, if you have previously built electronic circuits then probably building this one from the start won't be a problem for you, here's the design: https://homemade-circuits.com/2015/05/simplest-pwm-modified-sine-wave.html. I am an electrical engineer but not so much into inverter.
Your problem made an interesting reading so thought of of understanding it more. We need to confirm that 1.0 There is no load being fed by circuit not routed through distribution box. 2.0 Confirm the working of indicating meter by using clip on ammeter, before and after 5 PM. Measurement should be done at output wires from inverter to box.
3.0 In case clip reading donot change in correspondence with panel meter, we may doubt problem inside inverter. 4.0 during daytime, switch off all load and confirm meter reading. These observations may lead us in understanding the problem.
What would happen if the AC and DC 'collide' within the power inverter? The inverter is connected to solar batteries, and it is used as an alternative to power the lighting in our house.
But someone turned both the main circuit breaker for the lighting, and the alternative circuit breaker 'on'. The circuit breaker connected to the power inverter and the solar batteries got 'tripped'. When i turn off the main circuit breaker and turn on the alternative solar circuit breaker, it is not working. It seems that the power inverter got broken when the two circuit breakers were turned on at the same time. Is there any way to fix the inverter?
I have a 2200W inverter to provide back up power for a sump pump. The inverter goes into overload (and blows an inline 15A 125V fuse) every time anything is plugged into the output plug. This particular inverter is designed to plug into wall AC to keep the batteries charged and pass through 'wall' power when it is available.
When power goes out it switches to battery power and inverter mode to power my sump pump. Whether the unit is passing through 'wall power' or in 'inverter' mode as soon as anything is plugged into the ouput outlets there is a 'buzzing' / 'vibraton' and an overload condition.
It seems like there is a short occurring when anything is plugged into the outlet. What could be the problem? I am not sure where to look for the shorted condition. Why would it only short when something is plugged in.
And why would it short when passing through current from the wall as well as when producing inverted power from the batteries? Note - this unit used to function normally. So it must be a worn or failed part / condition. I think some internal circuit stage might be malfunctioning and shorting the output possibly through a relay, on detection of a load. You can troubleshoot it by tracking and locating the 'load' wires which may be terminating from the trafo output, and temporarily disconnect everything that might be associated with these wires.after doing this you could check whether the problems persists or not.if still it continues to behave in the same manner then the problem could be assumed to be on the primary side. Hello good sir, I have a 300W 12 V DC to 230 V AC Mascot Inverter in my boat, which supplies a tv-screen and an underwater camera. The problem is that most times the screen will not turn on, it just makes a ticking sound.
But when I pull the plug and wait a couple of minutes with the engine running, it will usually start when I plug it in again. I measured the inverter inlet and it says 16 V, and the outlet is only around 190 Volts.
Should it not be around 230 Volts? I have a 12 V 125 AH battery. I'm a rookie when it comes to electronics, so I hope you'll have an idea whats going on.: Regards.
Hi Randy, your inverter problem appears to be similar to Benz's inverter problem.it's really surprising how the manufacturers missed the reverse polarity protection, which is extremely important in such equipment which require external battery connection. Anyway, the problem is definitely repairable. You could probably follow the positive line and check the stages which are being connected with this line. Most probably you would find this line going to the PCB of the inverter which might be having many associated ICs and other devices.so you could check whether these ICs are directly involved with the positive line or not, if yes, then it would imply that these devices could have been damaged due to the wrong battery connection. Hello Swagatam, I have a Hyundai 3.4kw inverter generator (HY3600SEI).
The generator engine starts first time and runs up to speed. The green AC ready light comes on for about 3 seconds and then go's off (power is removed from output socket) and the Red overload light comes on and stays on.
If I apply a load (any size load up to 3400 watts) within the 3 second time frame that the generator starts and energizes with green light (Power available), the load will power up and run for hours producing power. If no load is applied, red light comes on and power is no longer available without turning off engine and restarting. Thanks Warren. Hello Swagatam, i have been following the conversations you have had with different people with different questions, i am really impressed with your intelligence and willingness to help other people, thanks.
However i have my own problem which believe you will help. My inveter is 500 watts and i use it for only the TV which is 100 warts and 3 energy saver bulb 12 watts each. Now my inverter is working but the green light is off and the voltage gauge is down, what could be the problem and what are the dangers if possible any suggestions for fixing the issue? Good Morning Sir, I have recieved a lebanon made inverter to repair that has one transfo (used for both charging and DC-AC ivertion), Six mosfet (IRFP250n) each three are in parallel, Inverter board, A big relay close to the transfo and Battery charging ciecuit. The inverter is not working. I check it following the guidlines you provided above and I found out that, the inverter can work when 220 AC power applied to it but it cannot work on battery.
The foulties area are summarised bellow. It cannot charge the battery while the transformer has provided the DC voltage through the help of the Big relay.
If battery is connected, a relay on battery charging board is moving. Also, there are two big resistor of about 10 or 15watts connected in parallel that spilt into pieces (unfortunatelly it has no details on it, I would have change it and try the inverter) but, when I arranged it and apply AC power I can see the charging LED lighting. But to me, I think this resistors are what prevent inverter to accept the battery, because they are working as a trigger. 1) Sir could you please suggest what is wrong?
2) And, what type of the resistors should I try? Thank you Sir.

Hi swagatam I have a sukam 750va inverter. For the last few days its giving unique problem whenever i connect only a ups through it, ups starts giving fast tic tic sound of relay and when i connect it to a power point which isn't through inverter, it works fine. And when i switch on a tubelight or a fan ups' relay tic tic sound instantly stops. What could be the possible reason. I have measured voltages through and without inverter it's almost same. However when i measured dc voltage which charges the battery it was 13.9v instead of 12. Please help me in this.
I am sorry if I am posting this question as a repetition and maybe it was already answered. I connected my new 2000 KVA inverter today and fear due to a short circuit in wiring have busted it. (It showed a fault related to short circuit us well). Now ups is working only on main power supply only.
As soon as I switch off the main, Inverter also dies instantaneously. L intend to repair it or alteast check for the fault myself. Can you please guide from your experience what can the fhoblem be. Hi Swagatham I have a 4 year old 850VA Sukham inverter backed up by a 150AH Exide Tall Tubular battery of the same age. Sometimes when the power goes off, the inverter immediately goes off to low battery. But when I checked the battery via a multimeter, it showed 12V.
If I keep inverter off for some time( say 30 mins) and switch on the inverter it starts working properly(ie there is no low battery siren). In order to test if the battery was weak, I tested the battery by switching off the main power so that the inverter starts working. At that time the inverter worked properly for about 3 hours with lights, fans, TV switched on. I am not able to replicate this problem at will. So this is a random problem which happens. What could be the issue?
Hi Swagatham, I recently bought an Exide ECO 900 Inverter (Square wave inverter) and I am facing the below issues. The output voltage of Inverter shows 290V when I use it with 2 fans and one nightlamp, And the voltage getting drop to 250 to 260V only if I use more appliance at a time (3 Fans, 3 Tube light, 1 LED TV). And it is hard for me to use all these appliance at night while sleeping. I am scared since the 2 Fans are running too fast at night while using Inverter specifically having a Infant baby in my Home. Need your advice asap to get this issue resolved please. Thanks, Santhosh.
Hi Swagatam, Thanks for your advice:-) Now I have add the Fan regulator to reduce the speed. I am already using a battery of 12V with 200AH to have more back up. May we have any other suggestion instead of replacing the battery, since I already spent a more on buying the above battery? Also If I replace the low voltage battery, I doubt if I could use all other appliance at a time when needed. And adding a stabilizer from Inverter output will work out for this issue? Also need to know is there any fault in my Inverter or this is the general character of Square wave inverter. If yes, i shall replace my inverter with the better quality one, since I bought the Inverter via Online only 5 days back, so I return it back as damaged product.
Thanks, Santhosh. I have a modified sine wave inverter that can has a maximum rated power of 1000w, now i was messing around with it and trying to connect it to my room (from an electrical port with an on-off switch) but i forgot to turn the switch off and as a result it connected to the main house electricity and thankfully i only blow one my electric switches but i managed to get it back running using a spare plug-in cable, and now my inverter will turn on with fault, switch to power for a second then back to fault instantly and permanently, what possible cause that made the inverter goes like that? What is the possible issue/broken part inside it?
Hi, what kind of charger are you using? Does it contain some kind of critical sensing circuitry?
Because if the charger is a simple power supply then this should not happen, may be your charger's sensing circuit is detecting something in the inverter and not allowing the battery to charge while it's connected. Also make sure the inverter is not consuming anything from the battery while it's idle.check this by connecting an ammeter in series with the positive wire which connects the inverter with the battery (+).if it's not consuming anything then it's fine and you may try a different charger unit and see the response. Swagatham I have truepower 850va square wave inverter,I want to replace its pcb with sukam torque pcb 900va so I want some help to buy the correct components which will protect my appliances from burning out. So can you help me to get the specs of the components which are circled in the red color from attached photo. I hope to check this link to know what I mean: https://disqus.com/home/channel/engineering/discussion/channel-engineering/howtoinstallsukamtorquepcbontruepowerinverter/. I bought a normal pure sine wave inverter and a separate solar charge controller. The power in my country 3 hours off then 2 hours on then 3 hours off then 2 hours on, the power keeps running in that pattern.
To protect my battery I have to turn off my inverter to prevent charging from inverter but my question is that, is there any relay could do the following job: when power is there inverter charge the battery and solar charge controller stop working but when power cuts off, solar charge controller start charging the battery.
