Rectifier
A device which convert alternating current or voltage into direct current or voltage IS known as rectifier . The process of converting AC into DC IS caned rectification .
Half-Wave Rectifier
A half-wave rectifier converts the half cycle of applied AC signal into DC signal . Ordinary transformer may be used here .
Full-Wave Rectifier
A full-wave rectifier converts the whole cycle of applied AC signal into DC signal . Centre top , transformer is used here .
[ Half-wave rectifier converts only one-half of AC Into DC while full wave rectifier rectifies both halves of AC input .]
