Draw the circuit diagram of a half waverectifier. Explain its working. What is thefrequency of ripple in its output?​

Answer»

Answer: Single-phase circuits or multi-phase CIRCUIT comes under the rectifier circuits. For domestic applications single-phase low POWER rectifier circuits are used and industrial HVDC applications require three-phase rectification. The most important application of a PN junction diode is rectification and it is the process of converting AC to DC.

Explanation:  a single-phase HALF-wave rectifier, either negative or positive half of the AC voltage flows, while the other half of the AC voltage is blocked. Hence the OUTPUT receives only one half of the AC wave. A single diode is required for a single-phase half-wave rectification and three diodes for a three-phase supply. Half wave rectifier produces more amount of ripple content than full-wave RECTIFIERS and to eliminate the harmonics it requires much more filtering.
