Refer to Problem 9.38 and assume a load voltage waveform as shown in Figure P9.40. Also assume:
|io|avg = 60 mA |vo|avg = 5 V |Vripple| = 5%
vline = 170 cos(?t) V ? = 377 rad/s
Determine:
a. The turns ratio n.
b. The capacitor C.
Problem 9.38
In the full-wave power supply shown in Figure P9.38 the silicon diodes are 1N4001 with a rated peak reverse voltage of 25 V.
n = 0.05883
C = 80 ?F Ro = 1 k?
vline = 170 cos(377t) V
a. Determine the actual peak reverse voltage across each diode.
b. Explain why these diodes are or are not suitable for the specifications given.
