4.69 A full-wave rectifier circuit with a 500-2 load operates from a 120-V (rms) 60-Hz household
supply through a 6-to-1 transformer having a center-tapped secondary winding. It uses two silicon
diodes that can be modeled to have a 0.7-V drop for all currents. What is the peak voltage of the
rectified output? For what fraction of a cycle does each diode conduct? What is the average output
voltage? What is the average current in the load?
Hint: the average output voltage can be obtained by using the equation below (see plots below too),
but you will need to find out the conduction angle 0 first.
