LTspice square wave inverter

[akshaydavid95]

Hey guys,

So I need to create a square wave inverter on LTspice to run some simulations. I've created it and to test it I put a resistance across its output. Without the resistance it gives me 240V as desired but when I add the resistance, the voltage drops down.
I'm not sure if its something silly but how do I keep the voltage at 240 when there's a load?

Thanks,
Akshay

Why all the MOSFETS, etc? Why not just use the PULSE generators themselves?

Hey Bwaslo,

This was for a research project I'm working on for uni so I wanted to make sure I didn't take any shortcuts.
But a friend at worked pointed out I need to select the right kind of Mosfet. I selected ones that were able to deliver a high current and it works fine.
Previously generic Mosfets' rating were too low I think.

But problem fixed, the thread can probably be closed.
