Circuit Diagram of Bridge Rectifier:

  • Here, during positive half cycle, the diodes D1 and D3 are forward biased and the diodes D2 and D4 are reverse biased.
  • Whereas, during the negative half cycle, diodes D2 and D4 are forward biased and the diodes D1 and D3 are reverse biased.
  • The current flows in both half cycles of ac supply and hence we get output voltage during both half cycles of ac supply.
