Abstract:
Rectifier is a device which converts the alternating current (A.C.) power to direct current (D.C.) power. It is frequently necessary for such applications as electrolytic work, electroplating and charging of storage batteries. There are two types of rectifiers that have found wide industrial use are: (1) metal rectifiers and (2) mercury arc rectifiers. The term `Metal Rectifier' is widely accepted as covering a whole range of dry - contact rectifiers in which rectification takes place at the junction between a conductor and semi - conductor or between two semi- conductors of different properties. The ranges available from 6 V / 10 A to 24 V 500 A.
