Controlled Rectifier – Circuit, Types & Advantages
A controlled rectifier uses controllable semiconductor devices like thyristors, IGBTs, etc. We know that an uncontrolled rectifier gives a fixed dc output voltage,

The center-tapped and bride-type rectifiers are two different types of circuit constructions that converts both positive and negative cycles of ac into dc.
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.
