12VDC to 220VAC Inverter with 555 Timer. This simple 12VDC to 220VAC inverter circuit produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4. The 555 feeds its output (amplified by Q1 and Q2) to the input of transformer T1, a reverse-connected filament transformer with the necessary step-up turns ratio. Capacitor C4 and coil L1 filter the input to T1, assuring that it is effectively a sine wave. Adjust the value of T1 to your voltage.
where will be the terminals of the cell connected
PLEASE SEND ME THE TRANSFORMER DESIGN COMPLETE TO MY EMAIL ID.

1 1/2 size of bobbin 2000watts inverter
How can connect the output pin of the ic555 to transistor tip41a and tip42
Where can i get the type of transformer?
What type of potentiometer from this circuit??it is linear taper potentiometer?
an explanation of current load would be nice
Hlo sir may I use to same pnp transister in the circuit
