Advantage of center-tap Full-wave rectifier.
The ripple factor is much less than that of half wave rectifier.
The rectification efficiency is twice than that of a half wave rectifier. For a full wave rectifier, the maximum possible value of rectification efficiency is 81.2 % while that half wave rectifier is 40.6 %.
The DC output voltage and DC load current values are twice than those of a half wave rectifier.
Disadvantage -
It is expensive to manufacture a center tapped transformer which produces equal voltage on each half of the secondary windings.
The output voltage is half of the secondary voltage, as each diode utilizes only one half of the transformer secondary voltage.
The PIV (peak inverse voltage) of a diode used twice that of the diode used in the half wave rectifier, so the diodes used must have high PIV.

A Central tapped rectifier uses a central tapped transformer which is a two-phase and three wire transformer and is generally used in rectifiers.
Explanation:
- There are the following advantages and disadvantages of the central tapped full-wave rectifier.
Advantages:
- It rectifies the full-wave and its efficiency is double as compared to the half-wave rectifier.
- The ripple factor is approximately one-third as compared to the half-wave rectifier.
- The DC load current and DC load voltage are double as compared to the half-wave rectifier.
Disadvantages:
- It is difficult to make the central tapping.
- Its manufacturing cost is very high.
- One diode works only in half cycle.
