Advantages and disadvantages of center tapped full wave rectifier

Advantages of a center-tapped full-wave rectifier:
  • The ripple factor is much less than that of a half-wave rectifier.
  • The DC output voltage and DC load current value are twice those of a half-wave rectifier.
  • The rectification efficiency of the full-wave rectifier is double of that of a half-wave rectifier.
  • The output efficiency is high because the AC supply delivers power during both half cycles.

Disadvantages of a center-tapped full-wave rectifier:

  • It is expensive to manufacture.
  • The output voltage of the secondary voltage as each diode utilizes only one half of the transformer secondary voltage.
  • It is difficult to locate the center on the secondary for the tapping.
  • The PIV of the diode used twice that of the diode used in the half-wave rectifier so the diode used must have high PIV.
