A diode bridge is an arrangement of four (or more) diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input.. The main function of all these rectifiers is the same as the conversion of current but they not efficiently convert the current from AC to DC. So it eliminates the draw back of center-tap rectifier i.e the size of the transformer in high power applications. 6) In full wave bridge rectifier , voltage regulation is good as compared to half wave bridge rectifier , or we say that in other words that , it is better than half wave bridge rectifier. Full wave rectifier requires center tapping of the secondary winding of the transformer.

Imax  . The large DC power output. There are two types of full-wave rectifiers — the center-tapped full-wave rectifier, which requires a center-tapped transformer, and the bridge rectifier, which does not need a center-tapped transformer. We can define bridge rectifiers as a type of full-wave rectifier that uses four or more diodes in a bridge circuit configuration to efficiently convert alternating (AC) current to a direct (DC) current. This type of single phase rectifier uses four individual rectifying diodes connected in a closed loop “bridge” configuration to produce the desired output. The bridge rectifier provides full wave rectification and has the advantage over the full wave rectifier using two diodes that no centre tap is required in the transformer. half-wave rectifier: Halbwellengleichrichter {m} full-wave: Vollwelle {f} electr.
