Simple Inverter Circuit 12VDC – 220VAC

This simple inverter circuit 12VDC – 220VAC contains a central part, the CMOS 4047, and converts a 12V DC voltage to 220V AC voltage. The 4047 is applied as being a astable multivibrator. At pin 10 and 11 we obtain a rectangular symmetrically signal that is amplified by two Darlington transistors T1 and T2 and lastly reaches the secondary coil of a transformer network (2 x 10V/60VA).

Inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.
Main coil terminals voltage is 220 alternative voltage. To acquire a improved functionality use a toroidal core transformer with lowered losses. With P1 the output frequency could be regulated in between particular limits (50-400Hz).
