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
What is the main difference between a bridge rectifier and a full wave rectifier?
Both the bridge rectifier and the full-wave rectifier achieve the same thing. They rectify the AC input on both opposing phases so as to minimize ripple time and voltage. The difference is that a bridge rectifier consists of four diodes arranged in a bridge, so the input needs to only be single phase AC, while a full wave rectifier consists of two diodes, but needs a split phase AC source, such as provided by a center tapped transformer winding. Also, the bridge rectifier presents two junction drops in the output, because there are always two diodes in series, while the full-wave rectifier presents only one junction drop in the output, because there is only one. It is a trade-off.
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.)
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.)
What is full waves rectifier?
The full wave rectifier is a means of converting alternating current (ac) into direct current (dc). It is done with either the use of 2 diodes coming off a center tapped transformer, or by using a bridge rectifier, which conists of 4 diodes ganged together in a certain configuration. As it's name implies, it converts both the positive going and the negative going parts of the sign wave into useable dc, and therefore is more efficient than a half wave rectifier, which only converts 1/2 of the complete sign wave into useable dc.
Which one is good center tap or bridge wave rectifier?
Either, it depends somewhat on application.

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.
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 to use four diodes when two diodes also can serve the purpose in bridge rectifier?
Four diode rectifier not require a center tapped transformer.
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.
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
What are advantages of bridge rectifier?
A bridge rectifier will rectify both halves of a sine wave and give "continuous output" through 360 degrees of the input. Oh, and you don't need a center-tapped transformer to use it.
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.

Types of rectifier?
There are basically two types of rectifiers one is the half wave rectifier and the other is the full wave rectifies. The full wave rectifier is further classified into two types namely the bridge rectifier and the center tapped rectifier.There are also silicon controlled rectifiers nowadays.
