Problem# 1

A half-wave uncontrolled rectifier with a filter capacitor has a 120 V rms 60 Hz ac source. The load is 50 W.

(a) Determine the value of a filter capacitor to keep the peak-to-peak ripple across the load to less than 1.5 V.

(b) Determine the average and peak values of diode current.

(c) Validate the results using PSpice simulation.

Problem# 2

A controlled half-wave rectifier has a 240 V rms, 60 Hz ac source. The load is a series resistance, inductance, and dc source with R = 100 , L = 150 mH, and Vdc = 96 V. The delay angle is 60o. Determine

(a) the power absorbed by the dc voltage source,

(b) the power absorbed by the resistance,

(c) the rms voltage across the load.

(d) Validate the previous results using PSpice simulation.
