This inverter circuit changes 12 Volt DC voltage to 22o Volt AC voltage
The inverter circuit uses CMOS 4047 IC that serves as
astable multivibrator which produces a square signal on pin 10 and pin 11.
The output of IC 4047 is amplified by a transistor circuit
Darlington T1 and T2 that results to feed to the transformer (2 X
10V/60VA) and produce an output transformer of 220 volt AC .
