Question

What is need of rectifier? Give the types of rectifier?

Answer 1

the rectifier as its name rectifies the positive negative cycle of alternative current.

and thus making it a nearly direct current to be used in the electronic machines.

or in short it converts a.c current in to d.c current

types are

half wave rectifier

full wave rectifier, center tap rectifier.

bridge wave rectifier.

Answer 2

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. The process is known as rectification, since it "straightens" the direction of current.

There are three common types of rectification:

Half wave rectification.

Full wave rectification.

Full Wave Bridge Rectification.
