Question

37. In a single phase supply, half wave rectifier requires :
​

Answer 1

Answer:

Explanation:

Half-Wave Rectification. In a single-phase half-wave rectifier, either the 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
