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.

How many diodes in a bridge rectifier?

Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.


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).


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.


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.)


What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?

They both have the same current.


Which harmonics is present in full bridge rectifire?

Since the output of the rectifier is a close approximation of a sawtooth waveform, then all harmonics starting at the second harmonic are present in the full wave bridge rectifier output.


What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?

in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.


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 happens to the output when one of the diode becomes open in full wave bridge rectifier?

How many diodes in full wave rectifier?

Depends on the number of phases.single phase uses 4 diodesthree phase uses 6 diodes


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
