Question

2. In the following circuit, v, 20 Vrms (rms value). a) Determine the value of capacitor needed to provide filtering so that the voltage does not drop below 26 V. The load resistance Rioad may vary from 1.5 kQ to 2.5 kQ. Assume the diode is ideal (VON 0 V). b) Sketch v, and the output vout waveforms. c) The filter capacitor often represents a significant economic factor in terms of cost, size, and weight in the design of rectifier circuit. How can you modify the rectifier circuit with a reduced capacitor value while keeping the same level of ripple voltage as in (a)? What is the new capacitor value? Show your modified circuit. 20V C load 60 Hz
