Transformer Action

Transformer action is a phenomenon by which EMF(Electro-motive force) is induced in from one coil to the other coil by electro magnetic induction. It is the basic principle of electric…

Difference between Higher potential and lower potential

Before getting into the topic, we have to keep two points in mind.1. Conventional Current flow. (The way Current is said to flow historically)2. ‎Actual current flow. (The way Current…

Working of Diode rectifiers (Uncontrolled rectifiers)

Introduction

Circuits that are used to convert the Alternating Current (AC) input power into a Direct Current (DC) output power is known as rectifier circuits. Rectifiers are found in almost all equipment, from a low voltage battery charger to High Voltage DC transmission systems. Basically, rectifiers are classified into Controlled rectifiers and uncontrolled rectifiers. In controlled rectifiers, semiconductor switches such as thyristors, BJTs, MOSFETs, IGBT etc are used. The output parameters of a controlled rectifier can be easily controlled with the help of semiconductor switches. In this article only the uncontrolled rectifiers are discussed. As the name indicates these rectifiers cannot be controlled externally. Controlled rectifiers are made up of a few diodes and conditioning elements such as capacitors.
