5. Rectifier
The rectifier converts the ac input voltage to a pulsating dc voltage There are two types of rectifier.
Half-wave rectifier
Full-wave rectifier .

6. Half-Wave Rectifier
When 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.

8. Wave form of Half wave rectifier

10. Full-wave Rectifier
The output of a full-wave rectifier is driven by both the positive and negative cycles of the sinusoidal input, unlike the half-wave rectifier which uses only one cycle.

12. Wave form of full wave rectifier

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.

14. Types of filter circuits:-
1. Shunt capacitor filter
2. Series inductor filter
3. Choke input LC filter
4. Capacitor input LC filter and
5. Π filter

16. Series inductor filter

17. Choke input LC filter

18. Capacitor input LC filter

19. Π filter

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.
