Principles of Rectification

BasicPrinciple of Rectification

Rectifiers change ac into pulsating dc by eliminating the nega Live half’cycles or alternating the ac voltage. Only a series of sinewave pulsations of positive polarity remain. An ideal rectifier may be thought of as a switch that closes a load circuit whenever the polarity of the alternating voltage is positive, and opens the circuit whenever the alternating voltage is of negative polarity. A switch
