The PS consists of a transformer, a 3-phase controlled rectifier, and a low pass filter to reduce the noise on the output depicted in Fig. 1. In the case of a 3-phase controlled rectifier, the thyristors conduct whenever they are forward biased and the gating signal, delayed by firing angle , is present. The purpose of delaying the gating signal is to regulate the dc voltage level.
