Now the current flows along points N, E, A, B, C, F and M. Now D 2 and D 4 are forward bias and D 1 and D 3 are reversed bias. Hence the current flows along point M, E, A, B, C, F and N producing a drop across R L.ĭuring the negative input half cycle secondary terminal N becomes positive and M is negative. Diode D 1 and D 3 becomes forward biased whereas D 2 and D 4 are reversed bias. A resistor is connected in the circuit where rectified output voltage appears called load resistor R L Bridge Rectifier Current Path Negative Cycle Bridge Rectifier Current Path Positive Cycle Bridge Rectifier Output Waveform Working of Bridge Rectifierĭuring the positive input half cycle terminal M of the secondary is positive and N is negative. So due to this type of circuit is named bridge rectifier. As shown in the given diagram of full wave bridge rectifier it consists of four diodes under the condition in which four diodes are connected the called bridge circuit.
