Circuit Operation

The three-phase fully-controlled bridge rectifier with a purely resistive load is shown above. With any single-controlled rectifier circuit, the load current is unidirectional. Hence when the output voltage of the bridge tends to become negative, the load current is zero and the conduction is discontinuous, with the output voltage clamped to zero volts. The operation of this circuit has been described in detail in the previous page.
