MOSFET Power Inverter 500W using RFP50N06

MOSFET power inverter 500W

Another MOSFET power inverter which capable to deliver 500W electric power. The inverter build using MOSFET power RFP50N06, convert DC input 12V and give you AC voltage output 110V-220V.


Inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.

Circuit Notes:

  • The LT1013 offers better drive that the LM358, but its your choice.
  • The Power transformer must be capable of handling the chosen wattage output.
  • Appropriate Heat Sinks are Necessary on the Mos-Fets.
  • This MOSFET power inverter circuit will provide a very stable “Square Wave” Output Voltage.
  • Frequency of operation is determined by a potensiometer and is normally set to 60 Hz.
  • Various “off the shelf” transformers can be used.
  • 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!
