Peak Inverse Voltage (PIV) of bridge rectifier

Let us consider the instant the secondary voltage attains its positive peak value Vsm. Now diodes D1, and D3 are conducting whereas diodes D2 and D4 are non-conducting being reversed biased. The conducting diodes D1 and D3 have almost zero resistance (i.e. zero voltage drop across them). Point B has the same potential as point A and similarly point D has the same potential as point C. The entire voltage of the transformer secondary winding, Vsm is developed across the load resistance RL. The same voltage i.e. Vsm acts across each of the non-conducting diodes D2 and D3. Thus

PIV = Vsm
