In the full-wave power supply shown in Figure P9.38,
n = 0.1
C = 80 ?F Ro = 1 k?
vline = 170 cos(377t) V
The silicon diodes are 1N914 switching diodes (but used here for AC-DC conversion) with the following performance ratings:
Pmax = 500 mW at T = 25?C
Vpk?rev = 30 V
The derating factor is 3 mW/°C for 25°C < T ? 125°C and 4 mW/°C for 125°C < T ? 175°C.
a. Determine the actual peak reverse voltage across each diode.
b. Are these diodes suitable for the specifications given? Explain.
