Three Phase Bridge Inverter Explained

Circuit Diagram of Three Phase Bridge InverterWorking Principle of Three Phase Bridge InverterFormula of Line and Phase VoltageThere are two possible patterns of gating the thyristors. In one pattern, each thyristor conducts for 180° and in other, each thyristor conducts for 120°. But in both these patters the gating signals are applied and removed at 60° interval of the output voltage waveform. Therefore, both these models require a six step bridge inverter.
