Best Mosfet Inverter circuit Labels: 100 Watt to 500 Watt Inverter 0 comments This inveter is great and this inverter is really work too... Visit the original author's page here. This circuit will provide a very stable "Square Wave" output voltage. Frequency of operation is determined by a pot 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 be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output. The power leads must be heavy enough wire to handle this high current draw! Appropriate Heat Sinks should be used on the RFP50N06 Fets. These Fets are rated at 50 Amps and 60 Volts. ** Other types of Mosfets can be substituted if you wish.
