You have been asked to design a bridge rectifier for a power supply. A step-down transformer has already been chosen. It will supply 12 V rms to your rectifier. The bridge rectifier is shown in Figure P9.43.
a. If the diodes have an offset voltage of 0.6 V, sketch the input source voltage vS (t) and the output voltage vo(t), and state which diodes are on and which are off in the appropriate cycles of vS (t). The frequency of the source is 60 Hz. b. If Ro = 1,000 ? and a filtering capacitor has a value of 8 ?F, sketch the output voltage vo(t). c. Repeat part b, with the capacitance equal to 100 ?F.
