Expert Answer:
Half wave rectifier:
1. A rectifier which rectifies only one half of each a.c supply cycle is called a half wave rectifier.
2. Half wave rectifier gives discontinuous and pulsating d.c. output. Half wave rectification involves a lot of wastage of energy.
3. In a half wave rectifier the frequency of output signal is same as that of input signal.
Full wave rectifier:
1. A rectifier which rectifies both halves of each a.c input cycles is called a full wave rectifier.
2. Full wave rectifier gives continuous and pulsating output.
3. In a full wave recifier the frequency of output signal is double than that of input signal.
