## Peak Inverse Voltage (PIV) of bridge rectifier

Let us consider the instant the secondary voltage attains its positive peak value V_{sm}. Now diodes D_{1}, and D_{3} are conducting whereas diodes D_{2} and D_{4} are non-conducting being reversed biased. The conducting diodes D_{1} and D_{3} 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, V_{sm} is developed across the load resistance R_{L}. The same voltage i.e. V_{sm} acts across each of the non-conducting diodes D_{2} and D_{3}. Thus

**PIV = V _{sm}**
