Advantages and disadvantages of center tapped full wave rectifier

Advantages:

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

• 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.
• The ripple factor is much less than that of half wave rectifier.

Disadvantages:

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

• 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.
• 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.
