Unformatted text preview: R L R = 1k + _ V o V + i L Fig. 2 2 a. Find V o with no load and V + = 20V. b. Find the line regulation ( v o / v + ) with no load connected and deduce the output voltage V o when the supply is 10% higher. c. What is the smallest possible load resistor R L that can be used while the zener operates at a current no lower than I ZK = I Zmin and while the supply V + =20V. Problem 3 Consider the half-wave rectifier circuit of Fig. 3. Let v S be a sinusoid with 15 V peak amplitude, and let R=1.5k . Use the constant-voltage-drop diode model with V D =0.7V. Fig. 3 a. Sketch the transfer characteristic (v O in terms of v S ) b. Sketch the waveform of v O c. Find the peak current in the diode d. Find the PIV of the diode. Due date: October 1, 2009 at 1:00pm.
