Power inverter driver board needed

[fabieville]

I bought a power inverter 2000watt 24v at 120vac version off ebay. The brand is KR Power and the driver board got damage.
do you know where can i get it to buy? or if someone has a similar one to my one they can open it and tell me the I.C numbers that are on the board so that i can try and replace them.

I see a part # on it which is D 85773

so do you think that this board that u suggest will work even thou mines has 16pin and this one has 17pins.
should i discontinue one of the pins and if yes which one should i remove or do i have to tie one of the pins with another pin.
can someone please tell me how to configure this board so that it can work.

Hi Fabieville,

In my Opinion the first photo you have shown, does not have the 32pin 8010 PWM Chip, ie it is not a EGS002 or the EGS003 plug in board.  But does look like it has 2 FET drivers, a strange 20 pin PWM chip ? and a Op amp etc.

The Chinese have done many many similar plug in boards for small inverters, and over the years i have seen many variants of plug in control boards.  However getting an actual bonifida replacement may be extremely difficult.

Have a search on alibaba aliexpress etc for small inverter boards that have plug in control boards, and spend some time looking at the plug in boards in close up.

Sorry i can not be more helpfull.

favieville,

I did a search and this is the closest that I can get to your board.

Your board has 16 pins but it looks like one pin is cut off.
This one has 15 pins and has a schematic, hopefully you can use it.

The board number is "PIC16F716 IR2110S" Search for that exact number.

It is sold on ebay, Alibaba and AliExpress.
