What are the advantages and disadvantages of full wave center tapped?

A: There is no advantage since the result is the same DC. There is no power increase however the voltage DC will double since a bridge can rectify whatever comes out of the transformer as opposed to full pacification. The loss will be an additional .7v due to the fact that current will flow trough 2 diodes but then again the higher voltage will be there to more then compensate the additional .7 volts

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 are advantages and disadvantages of full wave rectifier?
advantage - less ripple, possibly allowing use of less expensive filtering and regulating circuitsdisadvantages - more parts and/or more expensive parts needed in rectifier circuit
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.
What is the basic difference between a full wave bridge rectifier and a full wave center tapped rectifier?
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).
Can you make transistor with 2 diode?
Yes, if the transformer output is center-tapped; otherwise, no, a bridge rectifier requires four diodes, or six for three phase power. More technically correct, what we are talking about is a full-wave rectifier. A bridge rectifier is properly always four or six diodes.

Is 2 diode without center taped can befull wave rectifier?
No. For a full wave rectifier, you need two diodes and a center tapped secondary, or you need four diodes and a non-center tapped secondary.

Why can't we implement the center tapped full wave rectifier without center tapped transformer?
A center-tapped transformer and two diodes can form a full-wave rectifier that allows both half-cycles of the AC waveform to contribute to the direct current, making it smoother than a half-wave rectifier. This form of circuit saves on rectifier diodes compared to a diode bridge, but has poorer utilization of the transformer windings. Hence we do not use centre tapping for full wave rectification.Ashish sharmaAstt. ProfessorHIET, Shahpur, kangra(H.P.)

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.
