Inverters are often needed at places where it is not possible to get AC supply from the Mains. An inverter circuit is used to convert the DC power to AC power. For high power applications, thyristors are often used.

However, for low and medium power requirements, power transistors can be used. Here, a simple voltage driven inverter circuit using power transistors as switching devices is build, which converts 12V DC signal to single phase 220V AC.

The basic idea behind this circuit involves the working of a voltage driven inverter circuit. An oscillator is used to drive the semiconductor switches alternatively. Each of the switches allows the DC source voltage to appear across the primary of the transformer in alternate intervals, causing an alternating voltage to be developed across the primary.  This primary voltage is then stepped up to a higher voltage depending upon the number of turns in primary and secondary coils.
