Whenever there arises the need to convert an ac to dc power, a rectifier circuit comes for the rescue. There are mainly two types of rectifiers: Alternating current periodically changes direction, whereas direct current.

Like the half wave circuit, a full wave rectifier circuit produces an output voltage or current which is purely dc or has some specified dc component.
The rectifier converts the ac voltage to pulsating dc, which is smoothened by filter circuit.
In rectifier circuits, we use semiconductor switches that allow the conduction of current in one direction only such as diodes, scrs, mosfets etc. A rectifier is an electrical device that converts alternating current (ac), which periodically reverses direction, to direct current (dc), which flows in only one direction. Read about rectifier circuits (diodes and rectifiers ) in our free electronics textbook The forward biasing and reverse biasing.
Rectifiers are electronic devices or circuits that convert alternating current (ac) into direct current (dc). As mentioned earlier, a rectifier itself. A simple pn junction diode acts as a rectifier. The output voltage of the power supply is expected remain constant against variations in the load.
