Question

advantages of full wave over half wave rectifier

Answer 1

Answer:

The full-wave rectifier conducts on every half cycle, whereas the half-wave rectifier conducts on every other half cycle.

1. This halves the average current on each diode, halving the power dissipated by the diodes.
2. It doubles the ripple frequency, making filtering easier.
3. Since the ripple frequency is doubled, the peak-to-peak ripple voltage is approximately half, which means that less capacitance is required in the filter capacitor.
4. Since the peak-to-peak ripple voltage is lower, the head-room between filtered and regulated voltage is less, meaning less power is dissipated by the regulator
