A Full-Wave Bridge Rectifier circuit with a 5k2 load, operates from a 220-Vrms, 50-Hz household supply through a 12-to-1 step-down transformer as shown in the figure below. It uses 4 diodes, which can be modeled to have a 0.75-V drop for any current. 220 Vrms 50 Hz D. D. 40 www R D 12:1 a) Add a filter capacitor to the circuit, and find its value, such that the ripple voltage (v.) is 1% of the peak output (v. p). What is the average output voltage (vo_vg)? b) Find the peak diode current (in) and the peak inverse voltage (PIV) of the diodes.
