Types of Full Wave Rectifiers

A full wave rectifier is an electronic circuit that converts alternating current (AC) into direct current (DC), and it has two main types:

  1. Center-Tapped Full Wave Rectifier: It uses a center-tapped transformer and two diodes to rectify AC, commonly employed in low to moderate power applications.
  2. Bridge Rectifier: This type of bridge rectifier utilizes four diodes arranged in a bridge configuration allowing for AC to DC conversion without relying on a center tapped transformer. It is often employed in high power applications and compact circuits.


Full Wave Rectifiers

A full wave rectifier is a component, in electronics that converts alternating current (AC) into direct current (DC). Unlike a wave that only utilizes one half of the input cycle a full wave rectifier takes advantage of both the positive and negative halves of the input cycle resulting in a smoother and more efficient output. In this article, we will go through the types of full wave rectifiers how they work, their advantages and disadvantages as well and their applications.
