The rectifier uses a tapped transformer and two diodes and the tapping is grounded. A center tapped full wave rectifier is a circuit which makes unidirectional flow of current through the load during the full cycle of input voltage. Bridge rectifier has certain advantages over centre tap rectifier.
It possesses better transformer utilization factor, better voltage regulation etc. Center tapped rectifier convert both halves of the ac input cycle into dc output. The result of full wave rectification is an output voltage with a frequency twice. This is a fullwave rectifier, but compared with the centretapped solution it uses. Nevertheless, systems with a number of pulses higher than 12 normally obtained by combining. Two diodes are so connected across the terminals of center tapped transformer secondary terminals that one diode conducts for positive half cycle and another diode conduct for negative half cycle of the supply input. The center tapped full wave rectifier employs a transformer with the secondary winding ab tapped at the centre point c.
In the center tapped full wave rectifier two diodes were used. Both provide full wave rectification, but their working process is different. These are connected to the center tapped secondary winding of the transformer. Centre tap full wave rectifier circuit operation,working. The ripple voltage is less than that of half wave rectifier. Each diode in the full wave rectifier is alternately forwardbiased and then. A full wave rectifier circuit is fed from a transformer having a centertapped secondary winding.
