Electronic Circuit Analysis

Chapter 3

Rectifiers, Filters and Voltage Regulators

Learning Objectives

To get familiarity of structural details and fundamental concepts of

• DC sources as the supply voltages for amplifiers, radios, TVs, computers etc.
• DC sources may be battery for portable equipment but are very expensive for heavy use. An alternative is to convert cheaply available AC voltage from power lines to DC voltages.
• Principles of working of Rectifier circuits
• Use of Filter circuits to convert unidirectional voltage to DC voltage
• Working principles of ‘regulator circuits’ to produce stable DC output voltage
