As we know , AC current alternate its direction whereas DC current is unidirectional.
An electronic device called a rectifier uses one or more P-N junction diodes to change alternating current into a direct current.
Explanation
The rectifier is the device that converts AC to DC.
- Rectifiers are of two types : Full wave rectifier , Half wave rectifier.
- Full wave rectifier: A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into DC.
It consists of two diodes. The output DC is a continuous signal.
- Half wave rectifier: A half wave rectifier is defined as a rectifier that converts the half cycle of alternating current into DC..
It consists of one diode . The output DC is a discrete signal.
