Mainly diodes that handle a fair amount of power. When diodes are constructed in a "bridge", it usually means someone is trying to rectify AC to DC voltage in what is considered a "full wave". Both sides of the sine wave + and - are utilized to change the AC current into DC. Typically power diodes are used in this fashion. Crystal diodes or other types will not work in a bridge circuit as they cannot handle the amperage or wattage that typically is wanted. Power diodes are usually ones that handle 1 amp or more of current. Some power diodes can handle 60 amps or more if properly constructed in a heat sink dependent upon their ratings.

Are diodes rectifiers?
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
Purpose of bridge diode in a power supply?
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
What type of rectifier used in radar?
the usual semiconductor rectifier used in the microwave band is a gunn diode. Vacuum tube diodes are sometimes used too.
What is the use of bridge rectifier?
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.
Which rectifier is not directly operated from mains?
Because , the high voltage can destroy the diodes used in the rectifier .
How you convert the 220v AC to 220v DC?
You can make this conversion if a full wave bridge rectifier is used. Make sure that the diodes are rated for the voltage that is being used.
What are the applicaton of diodes?
Diodes can be used in the following domains:In rectifier circuitsin display circuitsas switches
Where can you find a bridge rectifier?
Bridge rectifiers are used in alternators and other electronic equipment that needs full DC current and can be bought at local electronic stores as well as the internet. Radio shack sells them also. A bridge rectifier is a 2 or 4 rectifiers that rectify AC current into DC. A full wave bridge usually consists of 4 diodes that rectify both the negative and positive swings of the AC current into DC. With the proper center wound transformer, only 2 diodes are needed. Search Google for a "full wave rectifier" diagram!!!
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.
Does the current rating of a diode change when it is used in a bridge rectifier EG A bridge made up from four 10 amp diodes would it have a different total current rating. DD?
A : A diode is an dumb animal he does not care how it is used all it cares is that its limitations are not exceeded
Where is a diode used?
A diode is used as a rectifier, clipper and to get square wave form. The combination of diode (bridge) is used for full wave rectification. It also used as a voltage controlar. Different types of diodes have different uses in different appliences.
How many diodes can be used in center tap type rectifiers?
There are two diodes in a standard center tapped configuration of a rectifier. This is per phase, so if you had a three phase system, each winding having a center tap, all of which are connected together, you would have six diodes.
