Making 25W Low Power Inverter circuit diagram


This low power inverter uses only 9 parts and turns 10 to 16VDC into 115V / 60Hz square wave power to operate AC equipment up to 25W.

The first section of the 555 timer is wires as an astable oscillator with R2 and C1 setting the frequency. The output is available at pin 5. The second section is wired as a phase inverter. That output is available at pin 9. Resistor R3 and R4 keep output transistor Q1 and Q2 from loading down the oscillator.
