This is a 500W DC-to-AC inverter circuit diagram which produces an AC
output at line frequency and voltage. 12VDC to 220V 50Hz inverter
circuit will power 220V or 110V appliances from 12V car battery. The
circuit is easy to make and is low cost. Use proper transformer. The
output (in watts) is up to you by selecting different power rating
transformer and power transistor rating. If you load electronic device
which require 120V AC, then use transformer with 120V in output.link
