Problem: It is required to use a peak rectifier to design a dc power supply that provides an average dc output voltage of 15 V on which a maximum of *1 V ripple is allowed. The rectifier feeds a load of 150 Q. The is fed from the line voltage (120Vrms, 50 Hz) through a transformer. The diodes available have 0.7 V drop when conducting. lf the designer opts for a full-wave bridge circuit: a) Specify the rms voltage that must appear across the transformer secondary. b) Find the required value of the filter capacitor. c) Find the maximum reverse voltage that will appear the diodes, and specify the PIV rating of the diodes. d) Calculate the average current through the diodes during conduction. e) Calculate the peak diodes current.
