    Am having a problem repairing vintron 350w and 180w inverters they tend to short the mosfet driver circuit which is dead end to repair couse its covered in a protective poxy . Link of the driver circuit below

    so can anyone provide equivalent circuit diagram to connect to the circuit to power the H bridge configured mosfet ( i know its the H bridge configuration couse the transformer has no center tap) couse this invetors are well engineered and so sad to se them go to waste just becouse simple driver circuit .

    i tried to swap driver circuit with working invter worked like charm

    pls help !!
