    Hello
    I want to build an ( DC to AC converter ) 12v , I draw a circuit but the output gives an AC forklift wave , not a sine wave .
    Is there any change i can do to make the output gives a sinewave or my design is right ?
    I uploaded the circuit as a pdf file .
    Thank you very much .

    Applying a squarewave to a transformer will not give you a sinewave at the output. Depending on frequency you will see a distorted squarewave or a sawtooth.

    You can transform this into a series resonant converter or drive your transformer with a sinewave modulated PWM...
