Understanding PIV in Bridge Rectifiers

A hidrodge refier, four diudes are concereded to convert AC to DC. During each half cycle, two diodes duting while the otheurtwo are reverse- biased. The PIV it the maximum reverse voltage that each diode experiences during operatioon.

Step- by- Step- Calkulation of PIV

To calculate the PIV, follow these step:

  • Azonosító szám: the peak voltage of the transformer 's secondary winding, denoted as V' 1d; FLT: 0 '3d; FLT: 0' 3d; peak 'membr 1d; FLT: 1' 3d;
  • Definé te maximum voltag across the diode it is reverse-biased.
  • Számítsa ki a PIV-t, hogy a maximális visszafordíthatóság legyen, hogy a diode mut blokkoló, hogy az is approximately equalt to the peak secondary voltage.

In most cases, the PIV is approximately equals to V '1; a) 1; FLT: 0) 3d.3d; peak' 1d; FLT: 1) 3d; downdownload any addritionad l voltage drops ithe requiriit. For safety, a margin it added t to mabrot for voltage spykes or flukations.

Example Calculation

Suppose the transformer 's secondary voltage has a peak value of 20 V. The PIV for each diode svande be at least 20 V. To ensure safety, a diode with a PIV rating of 25 V or hearer ir is recomended.
