    [​IMG] need help
    hello every one!
    i am building inverter of approx 300w i am using pic16f877a for driving the question is that i am using stp75nf75 stp75nf75 requires VGS=10v to get fully on so i am using optocoupler for providing 10v and controlling optocoupler through pic can anyone suggest me that the mosfet which i am using will be fine or any other suitable mosfet can be used to make the inverter work ???.

    Post the circuit.

    What is the peak output current and voltage of the inverter?

    What is the PWM frequency?
