The bridge rectifier is essentially full wave rectifier. It uses 4 diodes.

Working: During the positive half cycle, terminal A is positive wrt B. Diodes D1 and D3 are forward biased and the diodes D2 and D4 are reverse biased.

During the negative half cycle, Terminal A is negative WRT B. Diodes D2 and D4 are forward biased and D1 and D3 are Reverse biased. Current flows through d2, Load and D3.
