Rectifiers

A full-wave rectifier circuit converts alternating current (AC) to direct current (DC). It allows both halves of the AC waveform to contribute to the output current. This is achieved by inverting the negative half of the AC cycle. As a result, the output frequency of a full-wave rectifier is double the mains frequency. Given:

Mains Frequency = Hz

In a full-wave rectifier, every cycle of the AC input contributes two cycles of ripple. Thus, the fundamental frequency in the ripple output is doubled:

Ripple Frequency =

Therefore, the fundamental frequency in the ripple output is Hz.
