Question

explain full wave rectifier and half wave rectifier

Answer 1

Half wave rectifier:
One p-n junction diode is used.
Only half cycles of input AC signal is converted into rectified DC output.
No.of.DC pulses per second is equal to frequency of applied AC
Max efficiency is 40.6%

Full wave rectifier:
Two p-n junction diodes are used.
Both positive and negative half cycles are converted into rectified DC output.
No.of DC pulses per second of the output is twice the frequency of applied AC.
Max efficiency is 81.2%.
