A three-phase, rectified current produces a voltage ripple of ____ pulses per Hz.

Question

Quizplus · Accepted Answer

A three-phase rectified current produces a voltage ripple with six pulses per Hz because the rectifier circuit will produce six pulses per cycle or per Hz. The rectifier circuit will conduct when the voltage of the input waveform is greater than the voltage of the capacitor, which will happen twice during each half-cycle of the input waveform. As a result, the rectifier circuit will produce six pulses during each cycle of the input waveform, resulting in a six-pulse waveform.
