Simple 100W Inverter Circuit 12VDC to 220AC

Inverter Circuit 100W with 2N3055

Here the simple 100W inverter circuit which will convert the DC voltage of 12V from car battery to become an AC voltage of 220V. This inverter apply famous CMOS IC of CD4047 squarewave oscillator to generate 50Hz squarewave frequency and use power transistors of 2N3055 to amplify the signal from CD4047.


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.

The final step is increasing the high power 12V squarewave to become 220V by center tapped tranformer.
