Rectifier

A center-tapped full-wave rectifier circuit uses a center-tapped transformer and rectifying circuit which consists of two diodes for the conversion of ac power into dc power.

A full-wave bridge rectifier uses four diodes connected in a close-loop configuration which converts alternating current into direct current.

In a half-wave rectifier only either the positive or negative half-cycle of ac input is rectified, whereas, in a full-wave rectifier, both positive and negative half-cycles are rectified.

An uncontrolled rectifier is a type of ac to dc converter whose output voltage is fixed i.e., the output voltage is constant and cannot be varied.

The process of conversion of ac power into dc power is called Rectification. The device used for the rectification process is called Rectifiers.

In practice, there exists an inductance and resistance in the supply source. This inductance is known as source inductance LS and due to this the line commutation process of thyristor and
