If possible send diagrams and illustrations.

Answer 1

This is a difficult job, I'd hesitate to tackle it myself. It involves special transformers, high power devices, heat sinks, cooling, and lots more. Make a mistake and it all goes up in smoke.

Buy one for a few hundred dollars, probably less than you would pay for the parts.

But if you really want to, and you have lots of experience in power electronics, search googl for "inverter schematic" and you will find lots. Be careful in your transformer design, and also in your thermal calculations.
