Most of the circuits comprising of electronic components run on dc supply..
As DC supply is not available directly for us, we use either 230/12V or 230/18V transformer to stepdown the available 230V (in some countries it is 110v) and then convert it into dc using a rectifier.
As a bridge rectifier is more efficient than a conventional full wave rectifier, about 81.2%, it is widely used in such type of circuits.
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.
The bridge rectifier used to rework alternating present (AC) into direct current (DC).

It converts input AC supply to DC in positive as well as negative half cycles.
ANSWER: It rectify the input to twice the input frequency as pulsating DC
The same as in any rectifier circuit: allow current to flow in only one direction through the rectifier, thereby converting AC to DC.
bridge rectifier is the best rectifier.
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.
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.
Yes, if the diodes that the bridge rectifier are rated for 230V in forward and reverse voltages. Normally you can do a search for the part number on the internet and get specs there.
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
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.
bridge rectifier is the best rectifier.
how to make a bridge rectifier on breadboard
Merits a diode bridge rectifier is simple to build
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Use a full wave bridge rectifier.
Four diode rectifier not require a center tapped transformer.
you basically use rectifiers..like zener diode rectifier and full bridge rectifier..
Bridge Rectifier
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.
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
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.
