it is more preferable over center tapped rectifiers because you dont have to use special centre tapped transformer that has larger secondary windings thereby reducing the size and cost
it also has another advantage by the use of 4 diodes i.e. peak voltage sustained by each diode is half of that sustained by the diodes in center tapped system that uses only 2 diode. thus lifespan of bridge type rectifier is more.

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.
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 advantages of using the bridge rectifier over the center tapped rectifier?
you only use half the number of windings in the bridge comparing it to the center tapped , and in the bridge rectifier the peak inverse voltage that a diode must be able to sustain without break down is half of that in the center tapped PIV per diode: center tapped: 2Vm : bridge : 1Vm
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
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.
What is the advantage of using the bridge rectifier over the conventional full wave circuit?
Output voltage is higher!!!
Why bridge rectifier is prefered more over centre tap rectifier?
A: the only reason that can be is you get twice the voltage minus a diode drop. That does not means twice the power but actually a little bit less/
What is the advantage of using the bridge rectifier over the two diode form in the full wave rectification?
the ease of filtering their outpot voltages
Why full wave rectifier is preffered over half wave rectifier?
Efficiency is double in case of full wave rectifier.
Is there any application where a center tap rectifier is preferred over a bridge type rectifier?
yes, where only 2 diodes can be used for fullwave rectification. this was the case with vacuum tube power rectifiers (e.g. 5U4 & type 80). these tubes shared a common cathode between 2 plates, the plates were connected to the ends of the secondary, the cathode supplied the rectified B+ voltage to the filter, the centre tap was grounded.
Why use half wave rectification and what are its advantages over full wave rectification?
A full-wave rectifier will provide an output through both the positive and negative halves of the AC sine wave. The half-wave rectifier will only provide an output for half the cycle. The filtered outputs of both rectifiers can be "smoothed" well, but the higher the load on the half-wave rectifier, the more the output voltage will vary across a cycle of input power. This results in higher ripple and makes regulation a bit more difficult. The full-wave rectifier will provide an output through both the positive and negative halves of the sine wave. It effectively "inverts" the negative half of the cycle and provides two "pulses" of power per cycle as opposed to one pulse per cycle for the half-wave rectifier. The full-wave rectifier might use a pair of diodes and a center tapped transformer, or might use four diodes in a full wave bridge configuration and a transformer with no center tap.
What is the advantages of halt wave rectifier over full wave rectifier?
Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
