What type of rectification inverts the negative voltage peak to positive voltage?

Full-wave rectification is a process in which both halves of the input AC waveform are utilized to produce a continuous output. During this process, the negative voltage peaks of the AC waveform are inverted to positive voltage, resulting in a more efficient conversion of AC to DC. This method effectively doubles the output frequency and provides a smoother DC output compared to half-wave rectification, where only one half of the waveform is used and the negative half is discarded.

In full-wave rectification, the use of a center-tapped transformer or a bridge rectifier allows for the conversion of both positive and negative halves of the input signal. The result is a voltage that is consistently above zero, minimizing fluctuations and providing a more stable electric current – a significant advantage in various electronic applications. This rectification method enhances the overall performance of power supplies and other electrical devices that require a reliable DC source.
