Rictifier

Rictifier

A rectifier is a electronic device which converts alternating current to direct current . It is a static and unidirectional device. The process of converting AC into DC is known as rectification. A rectifier can take the shape of several different physical forms such as solid state diode, mercury or valves, silicon-controlled rectifiers and various other silicon semiconductor switches.

Rectifiers are used in various devices including

(a)DC power supplies.

(b)Radio signals or detectors.

(c)A source of power instead of generating current.

(d)As flame rectification to detect the presence of flame.

(e) High voltage direct current power transmission system and televisions.

They are two main types

1. Half wave rectifier

2. Full wave rectifier
