Above scheme diagram is the circuit diagram of low budget, easy built low power power inverter designed using IC 556 as multivibrator and transistor TIP120 to amplify the signal from multivibrator.

This low-power 25 watt power inverter circuit which makes use of only 9 electronic parts. The inverter turns 10V to 16V DC input into 60Hz, 115V square-wave power output to operate AC electronic devices approximately 25W. The very first section of the 556 timer chip is wired as an astable oscillator with R2 and C1 […]
