12 to 220 volts voltage converter electronic project

A 12 to 220 volts voltage converter electronic project can be designed using electronic diagram below. This 12 to 220 volts voltage converter electronic project is designed using CMOS 4047 integrated circuit, that converts a voltage of 12 volts DC into a 220 volt alternative. CMOS circuit 4047 is used as a multivibrator. From the output pins, pins 10 and 11 a symmetrical square wave is amplified by Darlington transistors T1 and T2, which ultimately reach the transformer secondary coil.
With the potentiometer P1 output frequency can be adjusted within certain limits (50-400Hz).
