it can be driven by a single source voltage, such as the untapped secondary of a transformer or directly from the power line.
The peak reverse voltage that can be tolerated is 2x the reverse breakdown of the diodes.

∙ 12y ago1) PIV of central taped rectifier is 2V. It means we have to use diodes of high ratings which is costly.
2) Transformation core saturation occures in this rectifier.

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 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.
What is the effect of inductive load on a single phase full wave bridge rectifier?
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
How does bridge rectifier control a DC motor?
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
How do you test a voltage rectifier?
If you actually mean rectifier (rather than regulator), then you can determine if it is performing its base function of converting alternating current to direct current by using a voltmeter. If the rectifier is functioning, you should read a percentage (which depends upon whether it is a half-wave or full-wave rectifier) of the AC peak input value on the DC range of a voltmeter. Using an oscilloscope, you can clearly view the half-wave or full-wave unidirectional (positive or negative only) pulses produced at the output of the rectifier. If the rectifier is blown and is conducting in both directions you will see nothing on a DC voltmeter range (the average value of an AC waveform is zero), and on an oscilloscope you will see the full peak-to-peak AC input waveform at its output.

Full wave rectifier using RC triggering circuit with diagram?
A full-wave rectifier (sometimes called a "bridge" rectifier) produces output current on both half-cycles of the input AC waveform. ******************************************** There are two types of full wave rectifier circuit. One uses four diodes in a "bridge"configuration and is fed from a simple transformer winding. The other uses two diodes and needs to be fed from a centre tapped transformer winding.
Why you are using the bridge rectifier in most of the circuits instead of full wave rectifier eventhough the output of both are same?
If diode in the bridge circuit becomes open the circuit will become a half wave rectifier instead, but if a diode in a full wave rectifier opens then the whole circuit becomes open. (No current flow). ************************************************************** The outputs of the bridge and the two-diode full wave rectifier are not the same. For the rectified voltage to be the same value, the two-diode full wave rectifier must be supplied from a centre tapped transformer winding, the total voltage of which is twice that necessary for the bridge rectifier circuit. Furthermore, the maximum d.c. which may be drawn from the centre tapped transformer/two-diode arrangement, assuming capacitive filtering, is the same value as the transformer secondary winding's capacity. In the case of the bridge, the maximum d.c. which may be drawn, also assuming capacitive filtering, is 62% of the transformer secondary winding's capacity.
What is the disadvantage of using a full wave rectifier?
The main disadvantage of a bridge rectifier is that it needs four diodes, two of which conduct in alternate half-cycles. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. This poses a problem when low voltages are required. Another disadvantage of bridge rectifier is that the load resistor R Land the supply source have no common point which may be earthed.
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.

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.
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.
