Why a full wave rectifier is preferred over a half wave rectifier?
The a.c. component, or ripple, produced by the 4-diode (full wave) bridge rectifier is the same as that produced by the 2-diode full wave rectifier. The bridge is connected across the secondary winding of a transformer. The 2 diodes of the other type of full wave rectifier are each connected to one end of a winding, but that winding requires a center tap. For any desired value of d.c. after rectification, the a.c. voltage of the 2-diode rectifier winding has to be twice that of the winding required for the bridge.
Why cant you implement centre tapped full wave rectifier without centre tapped transformer?
The center tapped full wave rectifier depends on two similar windings, each 180 degrees out of phase with respect to each other. You are only going to get that with a center tapped winding. Without the center tap, you need four diodes.
What is the role of center trapped transformer in full wave rectifier?
centre tap transform convert ac into full wave rectifeir dc .It needs only two diodes but efficiency is less.
Why bridge rectifier is prefer over center type rectifier for low voltage applications?
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
What is the advantage of using the centre tapped full wave rectifier?
By using a center tap, with the tap connected to ground you can use one winding for the positive AC swing and the other winding (both relative to the center-tap) for the negative swing. Thus, when the secondary windings can be connected to the AC inputs of a full-wave-bridge rectifier to harvest a bi-polar DC power source. i.e. - a positive DC voltage 'rail' AND a negative DC voltage rail, say for example you have a 24VAC center tapped secondary of a 110VAC transformer. With a full-wave bridge, the center tap becomes the circuit 'ground' (aka 'return') in a DC circuit.
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Explain the working principle of center Tapped transformer full wave rectifier?
Explain the working principle of center Tapped transformer full wave rectifier? A center tapped transformer full wave rectifier is a type of rectifier circuit that converts alternating current (AC) to direct current (DC) using a transformer and diodes. The working principle of this circuit is based on the use of a center tapped transformer. A center tapped transformer is a transformer with a secondary winding that has a center tap, which is connected to ground. The primary winding of the transformer is connected to the AC source, and the secondary winding is connected to the load resistor and the diodes. During the positive half-cycle of the input AC voltage, the upper end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the lower end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the direction of the arrow. During the negative half-cycle of the input AC voltage, the lower end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the upper end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the opposite direction of the arrow. As a result, the output voltage across the load resistor is a pulsating DC voltage that alternates between positive and negative values but has a DC component. The ripple voltage of the output is lower than that of a half-wave rectifier since it rectifies both half-cycles of the AC input voltage. The advantage of using a center tapped transformer in a full-wave rectifier circuit is that it allows the output voltage to be double the voltage of a half-wave rectifier using the same transformer.

What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.

Who is better among centre tapped rectifier and bridge rectifier?
It depends on what you're doing and what you have available. If you can find a good center tapped transformer with the target voltage, that will save you 2 diodes. If you're going for the "quick and dirty" solution and you don't have a center tapped transformer, a bridge rectifier is an excellent way to get dirty DC. ANSWER: The center tap will offer a .7 v advantage over the bridge. Be aware that power output does not change just the voltage increases
Difference between 4 diodes and 2 diodes rectifier?
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier *********************************************************** A two-diode rectifier is not always a centre-tap rectifier. If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage. (But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)
How many diodes does a center -tap type rectifier use?
Two
What does transformer 6-0-6 means?
Transformer 6-0-6 means it is a 12 v centre tap transformer which has 6v output with respect to its centre tap terminal at either end, while there is 12 v across the ends of the secondary. We can use either end terminal of transformer secondary and a centre tap terminal as line-neutral supply. This type of transformer is frequently used with a full-wave rectifier using two diodes, in this case to provide a 6 v supply.
