Single Phase Full Wave Controlled Rectifier (With R and RL Load) Or Converter

Single phase fully-controlled bridge rectifiers are known more commonly as AC-to-DC converters. Fully controlled bridge converters are widely used in the speed control of DC machines and are easily obtained by replacing all four diodes of a bridge rectifier with thyristors as shown.

A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC. Unlike halfwave rectifiers that utilize only the halfwave of the input AC cycle, full wave rectifiers utilize the full cycle.

The full wave rectifier is further classified into two types: center tapped full wave rectifier and full wave bridge rectifier.

Full Wave Bridge Rectifiers are mostly used for the low cost of diodes because of being lightweight and highly efficient. The important uses of the full-wave bridge rectifier are given below. Mobile phones, laptops, charger circuits. Uninterruptible Power Supply (UPS) circuits to convert AC to DC.

The peak inverse voltage coming across each diode is double the maximum voltage across the half of the secondary winding in Bridge converter. The transformer utilization factor (TUF) also more in bridge rectifier as compared to the center tapped full wave rectifier, Which makes it more advantageous.
