Rectifiers & AC to DC conversion

What is rectifier?

A rectifier is an electrical device that converts alternating current, which periodically reverses direction, to direct current, which flows only in one direction. 

Type

Half wave rectifier, full wave rectifier and bridge rectifier

Pin Identification

+ Positive output

- Negative output

~ Two opposite ends denotes AC input

Application

a. The primary application of rectifiers is to derive DC power from an AC supply. Rectifiers are used inside the power supplies of virtually all electronic equipment.

b. Rectifiers are also used for detection of amplitude modulated radio signals. The signal may be amplified before detection.

c. Rectifiers supply polarized voltage for welding. In such circuits control of the output current is required, this is sometimes achieved by replacing some of the diodes in a bridge rectifier with thyristors.
