Schematic Diagram

This schema is more of a DC to AC inverter, it uses a 555 IC as a low frequency oscillator, adjustable, adjustment can be done by the potentiometer R4 and frequency should be between 50-60 Hertz. The pulses from the IC 555 will go to Q1 and Q2 are amplified and sent to the transformer T1, which has its winding reversed. Capacitor C4 and coil L1 filter are the input to T1, it effectively ensures that a sine wave is formed.
