5 RectifierThe rectifier converts the ac input voltage to a pulsating dc voltage There are two types of rectifier.Half-wave rectifierFull-wave rectifier.
6 Half-Wave RectifierWhen a diode is connected to a source alternating voltage, it will be of alternately forward-biased, and then reverse-biased, during each cycle of the AC sine-wave.When a single diode is used in a rectifier circuit, current will flow through the circuit only during one-half of the input voltage cycle.For this reason, this rectifier circuit is called a half-wave rectifier. The output of a half-wave rectifier circuit is pulsating DC.
13 Power Supplies Consist of: Transformer – steps ac voltage up or down. Rectifier Diodes – change ac to “bumpy” dc.Filter Network – includes capacitors and inductors, smooths out the bumps.Voltage Regulator – keeps the voltage constant.Protection – usually a crowbar circuit.
20 Important Concepts Half Wave Rectifier: Simplest. Hard to filter well. Full Wave Rectifier:Easier to filter.Requires transformer with center-tap.Transformer secondary must be twice intended voltage.
