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).

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).

A power inverter is a device that converts DC (Direct Current) power into AC (Alternating Current) power. The AC output is usually 120 VAC, 60 Hz (USA domestic power) or 230 VAC, 50 Hz (International power). Inverters are usually used to supply AC power from DC sources such as solar panels or batteries
