Full Wave Bridge Rectifier
The bridge rectifier is the most commonly used full wave rectifier circuit for several reasons
(1) It does not require the use of center-tapped transformer, and therefore can be coupled directly to the ac power line, if desired.
(2)Using a transformer with the same secondary voltage produces a peak output voltage that is nearly double the voltage of the full wave center-tapped rectifier. This results in the higher dc voltage from the supply.

When D1 and D3 are on, D2 and D4 are off and vive versa. This circuit operation is illustrated in the fig.
The current direction will not change in the either condition.
