Unformatted text preview: Chapter 9, Problem 43. You have been asked to design a full-wave bridge rectifier for a power supply. A step-down transformer has already been chosen. It will supply 12 V rms to your rectifier. The full-wave rectifier is shown in the circuit of Figure P9.43. a. If the diodes have an offset voltage of 0.6 V, sketch the input source voltage ( ) S v t and the output voltage ( ) L v t , and state which diodes are on and which are off in the appropriate cycles of ( ) S v t . The frequency of the source is 60 Hz. Figure P9.43 Chapter 9, Problem 60. A Zener diode ideal i-v characteristic is shown in Figure P9.60(a). Given a Zener voltage, Z V of 7.7 V, find the output voltage out V for the circuit of Figure P9.60(b) if S V is: a. 12 V b. 20 V University of Wollongong School of Electrical, Computer and Telecommunications Engineering ECTE290 3 Figure P9.60...
