What are the advantages of a full wave rectifier over a half wave rectifier


Rectifier: A rectifier is a circuit that is used for converting AC supply into unidirectional DC supply. 

The advantages of a full wave rectifier over a half wave rectifier are -

(i) The average (DC) output voltage is higher than for half wave.
(ii) The output of the full wave rectifier has much less ripple that of the half wave rectifier producing a smoother output waveform.
(iii) The advantage of full-wave Rectifier over a half wave rectifier is the Ripple factor.
(iv) The rectification efficiency of full-wave rectifier is double of that of a half-wave rectifier.
(v) The full-wave rectifier conducts on every half cycle, whereas the half-wave rectifier conducts on every other half cycle.

(vi) It doubles the ripple frequency, making filtering easier.
