Rectifiers and Filters (A8205)

Learn the principles of AC/DC and solid-state theories.  Digital electronic theory is also introduced.

Prerequisites

This lesson is designed for participants familiar with AC/DC theory, electrical safety, electrical print reading, electrical connections, semiconductors and diodes. The ability to use electrical test instruments is also required.

Description

This lesson presents the basic operating theories of electronic power supplies, half-wave rectifiers, full-wave rectifiers, full-wave bridge rectifiers, capacitive input filters, and inductive input filters. The lesson shows how to calculate the expected DC output voltage for a half-wave rectifier, full-wave rectifier, and full-wave bridge rectifier.

Objectives

Identify and state the function of the major components in an electronic power supply.  Explain the operation of a half-wave rectifier circuit. Calculate the expected DC output voltage and recognize the appropriate output waveform from a half-wave rectifier. Explain the operation of a full-wave rectifier circuit. Calculate the expected DC output voltage and recognize the output waveform from a full- wave bridge rectifier. Explain the operation of capacitive and inductive input filters.
