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.

∙ 13y agoIn a half wave rectifier you need 2 x the AC voltage to get the same DC voltage. Along with this, you cannot get a positive and negative voltage like you can with a full wave rectifier. This is often a desirable thing to have in modern electronic circuits.

There is a large amount of ripple as the AC is chopped up into pulses of DC.

What are the advantage and disadvantage of full wave rectifier with filtre?
either less ripple or ability to use smaller filter
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.
How many diodes are used to make a half wave rectifier?
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
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 full wave rectifier is preffered over half wave rectifier?
Efficiency is double in case of full wave rectifier.
What are the advantage and disadvantage of full wave rectifier with filtre?
either less ripple or ability to use smaller filter
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
Which provide more power and why full wave or half wave rectification?
full wave rectifier, because in half wave rectifier only one p-n junction diode Ans 2. In full wave rectifier both negative & positive cycles are rectified , but , in half wave rectifier only the positive or the negative cycle is rectified . That's why full wave rectifier provides more power .
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.
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
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
What are the advantages and disadvantage of full-wave bridge rectifier?
The purpose of a bridge rectifier is to basically turn AC into DC. In a half wave rectifier you just eliminate the negative part of sine wave so you have positive cycle and then zero volts for 1/2 a cycle. In a full wave you flip the negative to positive so you have continually repeating positive halfs of the sine wave. So, it is easier to filter the full wave into DC with a capacitor and you get more average power. The down side is the bridge is slightly more complex.
Conclusions of full-wave rectifier?
A half wave rectifier is not as effective as a full wave rectifier. With a 1/2 wave, you are throwing away one hump of the sine wave...either positive or negative portion. With a full wave rectifier you get both humps...either positive or negative. The resultant effective voltage is much greater with a full wave rectifier, because there is very little time when the voltage is zero. The half wave is zero for 1/2 of the cycle.
What is the advantage of using the bridge rectifier over the conventional full wave circuit?
Output voltage is higher!!!
