1. What are rectifiers and their types?
A rectifier is an electrical device consisting of one or more diodes that allow the unidirectional flow of current. It basically converts AC into DC.
The rectifiers are categorized into three types namely uncontrolled, half controlled, and full controlled rectifiers.
2. Why half-wave rectifiers are not used in dc power supply?
The half-wave rectifier is used most commonly in low-power applications because the output amplitude is less than the input amplitude and there is no output during the negative half-cycle.
