100W DC Power Inverter Circuit

100W DC Power Inverter Circuit diagram

This is the circuit diagram of 100W DC power inverter. The circuit will convert 12V DC input to a 220V AC output. You can use this circuit for small electronic appliances such as small lamps, mobile phone charger etc.

This is very common inverter circuit. the CMOS 4047 used to be a multivibrator which generates frequency, and the power transistor has a function to amplify the output signal from the multivibrator.


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.
