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.
There are some disadvantages of center tapped full wave rectifier which are given below,
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.
