we estimate the ripple seen by the load so as to appreciate the regulation provided by the diodes. The diode bridge is a full-wave rectifier. The frequency fin of at the input of diode bridge is 60Hz, C1 = 100microfarads, R1 = 1k02, and the peak voltage produced by the transformer is 5V. (a) Assume R1 carries a relatively constant current and VD,on = 0.8V, estimate the ripple amplitude across C1. (b) Using the small-signal model of the diodes, determine the ripple amplitude across the load.
