Hi Brother, I have seen many videos on electronics here in sinhala. I wish to state that this is the one of best tutorial videos I ever found on here so far. And also I noticed that your using all branded and most expensive test and measuring equipments, such as Fluke, HP bench PS, and Tektronix scope etc and defenitley that shows the proffesionalism.I guess you must have been working abroad for sure. I would like to take this oppertunity to wish you all the best and please do upload more repair videos. Keep it up, Cheers.
Very useful video , i also had a similar issue had to change spwm board , igbts + some resistors now it works fine 😊 , keep it up your good work 👍

I'am a electronics hobbyist.A very practical and simple explanation.I watched your videos on inverter repairs and also subscribed to your channel.If possible can you give some tips on how to identify the actual power( watts) of an inverter by checking the components of the circuit.?i.e the MOSFETS.Most of the time as you know it's never what is advertised on the sticker.Thanks

The limiting factor in most designs is the core size of the transformer. So to give you a very rough idea... If you see a single transformer (one that is roughly the size of those used on atx power supplies) you can expect a wattage of around 300-350w, if you see two of them,.. Expect about 700w... And so on. Bigger the transformer higher the (potential ) wattage.. After that it depends on the mosfets and diodes used.

high side සහ low side දෙකටම SPWM දෙන්න පුළුවන් නමුත් අවශ්ය නැ , H Bridge circuit එක බැලුවොත් පෙනවා FET දෙකක් එකවර on වෙන්න ඕනේ එක AC Half Cycle එකක් ලබා ගන්න . එම කාලය අතරතුරදී එකක් on එකේම තියල අනෙකට විතරක් SPWM දුන්නාම ප්රමාණවත්
