Full Wave Bridge Rectifier. This type of single phase rectifier uses four individual rectifying diodes connected in a closed loop bridge configuration to produce the desired output. The waveform of the full wave bridge rectifier is shown below.

Full wave rectifier finds uses in the construction of constant dc voltage power supplies especially in general power supplies. The construction diagram of a bridge rectifier is shown in the below figure. The full wave bridge rectifier.
During the negative half cycle end a becomes negative and end b positive as shown in the figure below.
But diodes being cheaper than a center tap transformer a bridge rectifier are much preferred in a dc power supply. Another type of circuit that produces the same output waveform as the full wave rectifier circuit above is that of the full wave bridge rectifier. A bridge rectifier is a type of full wave rectifier which uses four or more diodes in a bridge circuit configuration to efficiently convert the alternating current ac into direct current dc. A center tap full wave rectifier has only 2 diodes where as a bridge rectifier has 4 diodes.
