I have an Sukam 600VA inverter in my home. As the unit become damaged suddenly, so i have decided to repair it. after couple of investigation what i found, all mosfet got damaged, all driver transistor got damaged and the PIC16F72 chip got damaged also. I have changed all of the components. but the problem is i dont have the code/hex file for the PIC16F72 chip.

Studying an Indian book named "Modern Digital Inverter" by BPB Publications, surprisingly I found the whole diagram (same to same) of my inverter, but unfortunately I didn't find any code there ..

I have attached the schematic here. Can anybody help me by giving the code files, that was programmed into PIC16F72 ?? :|

A company does not reveal source code or hex file of their products.
Even, it is difficult to get schematic diagram.
But you are lucky, you got it.
I think you should contact with that company for pre-programmed pic.
 

And bear in mind what might happen if someone tried to write new code for it. Would you be willing to risk trying it for the first time after replacing all the other parts? Even experienced programming people run through a debugging and testing cycle to make sure their code works properly and I doubt many would have the same model of inverter to try it out on.

How u decide controller or it's pin is damaged. It may work u check it by adding fuse link between Mosfet & DC bus. U check Output PWM
 


is this a sine wave inverter? if not the code can be generated .

This inverter is in square wave.
Mosfets are in push pull configuration,and being switched with 50hz pwm signal.
 

it is also possible to do sine wave in push pull configuration.
