Question

The turns ratio of a transformer used in a Bridge Rectifier is 2:1. The primary is connected to the power mains: 210V, 50Hz. Assuming the diode voltage drops to be zero, (a) calculate the DC voltage across the load resistor. (b) What is the PIV of the diode? If the same dc voltage is obtained by using Center tapped FWR, what is PIV?

WITH ALL STEPS

Answer 1

Output to secondary terminal

DC dutput to load resistance.

Output Dc is of 55V.

PIV in HWR is given as

Part:b

Let Vm is maximum voltage to center tapped FWR.

so only 77.78 voltage need at secondary terminal.

Now PIV in FDR for center tapped

I hope it helps you.

Thanks for asking.
