Figure below shows a simple power circuit diagram of a three phase bridge inverter using six thyristors and diodes. A careful observation of the above circuit diagram reveals that power circuit of a three phase bridge inverter is equivalent to three half bridge inverters arranged side by side. The three phase load. .
There are two possible patterns of gating the thyristors. In one pattern, each thyristor conducts for 180° and in other, each thyristor. .
