Differences in half wave and centre tap full wave rectifier.
Answers
Some of the major differences between a center tapped full wave and a bridge rectifiers are tabulated below.
Sr. No. Center Tapped Full Wave Rectifier Bridge Rectifier
1) A center tapped transformer is required. No center tapped transformer is required in bridge rectifier.
2) The peak inverse voltage (PIV) of diode in center tapped full wave rectifier is twice the transformer secondary terminal voltage. PIV of diode is equal to the transformer secondary voltage. Thus this type of rectifier can be used for high voltage application.
3) Two numbers of diodes are required. Four diodes are required for bridge rectifier.
4) The transformer utilization factor (TUF) is equal to 0.672. The TUF is equal to 0.810 for bridge rectifier.
5) The transformer size i.e. kVA rating required for center tapped rectifier is more. Transformer size requirement is less.
6) – A bridge rectifier using four diodes is more economical when compared with center tapped rectifier.
