A charger with 5-V, 1-A dc output is to be designed with a ripple voltage of less than 2.5 percent. Assume that a half-wave rectifier circuit (60 Hz) with a capacitor filter is used. The diode has a turn-on voltage of 0.7 V. (a) What is the size of the filter capacitor, C? (b) What is the PIV rating for the diode? (c) What is the rms value of the input transformer voltage needed for the rectifier? (d) What is the value of the peak repetitive diode current in the diode? What is the initial surge current at t=0"?
