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.


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 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).


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.


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.

Why dc output voltage of a bridge rectifier varies with the load current?

aA A: the output of a Bridger's rectifier will always follows proportionally to the load since it does not regulate the output it merely transform AC TO DC '

What is the advantage of using the bridge rectifier over the conventional full wave circuit?

Output voltage is higher!!!


What will be the output if you change the direction of diodes in bridge full wave rectifier?

The output will not change. Whichever side of the transformer is positive at any instant still has 1/2 of the bridge to conduct through.

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 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.


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.
