    I,am trying to build a transistorized power inverter with transistors that have a maximum ic current of 300 amps, what type of power output can I expect and also what considerations do I have make when building this project?

    Expect an efficiency from 50% to 75%. Given the input power, you can figure the output power. But the efficiency pretty much depends on the circuit and components you are using.

    I've search for high-current rated power MOSFET, but no luck so far. How about the idea to make many parallel coils with many independent driver for each coil to minimize the skin effect? I think you can easily find power mosfet rated for 50A+ and you can use 6 driven coil sets.

    Btw, do you wan square, modified sine, or true sine output? Just curious if you wanna share. :)
