A bridge rectifier, is a group of rectifiers (4 in a single phase) wired so that each half of an AC current is passed to respective positive and negative lines of a DC output.
It provides full wave rectification of AC into DC.

What are the disadvantages of bridge rectifier to center tap rectifier?
In bridge rectifier,two of the diodes are forward biased(i.e conducting current) at a time while in centre tapped rectifier 1diode is forward biased at a time.So,the flaw in bridge rectifier is that voltage loss is more in bridge rectifier than in centre tapped rectifier. e.g:for silicon diode loss=-0.7v (for centre tapp) loss=2*0.7=1.4v (for bridge)
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 an explanation of the bridge rectifier?
A bridge rectifier refers to a diode bridge of 4 diodes in a bridge configuration that provides some polarity of the output for either the polarity of the input or output.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
Why used to bridge rectifier?
The bridge rectifier used to rework alternating present (AC) into direct current (DC). bridge rectifier diagram and how it work :- A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally. /
What is the difference between full wave bridge rectifier and bridge rectifier?
Those terms are different names for the same thing. When properly connected, a bridge rectifier is always a full-wave rectifier. ANSWER: The difference is that twice the input voltage will be available to the output, That does not means twice the power.
What happens when one of the diodes is removed from the bridge rectifier?
It will degrade to a half-wave rectifier.
Can a bridge rectifier is possible with the help of two 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.
What are the two main types of bridges in electricity?
A 'bridge' rectifier. Forming a full wave rectifier of AC to DC. A Wheatstone 'bridge'. Where a fine balance is measured, across a bridge of resistors.
What are advantages of bridge rectifier?
because its PIV rating is less than half wave rectifier
Why you prefer full wave bridge rectifier rather than full wave rectifier?
You would use a bridge rectifier if the transformer is a simple winding with two ends. A full-wave rectifier with two diodes is used when the transformer secondary is centre-tapped.
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
Schemes of Full wave rectifier?
A full wave rectifier can be implemented in two ways a) Full wave bridge rectifier b) Full wave centre tap rectifier.
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 happens when a diod is shorted in a full wave bridge rectifier circuit?
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
