100Watt Inverter Circuit by IRF44 Mosfet
This inverter circuit will provide a very stable 230V Output Voltage. Frequency of operation is determined by a VR1 and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own for best results. Additional MosFets can be paralleled for higher power. It is recommended to Have a “Fuse” in the Power Line and to always have a “Load connected”, while power is being applied. The Fuse should be10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw

 
The pwm at IC1 CD4047 can be replaced with a 555 timer which is available in local stores.
