Unformatted text preview: in a power supply. The step-down transformer has already been selected and will provide 12V rms to your rectifier at a frequency of 60 Hz. a. Sketch the input source voltage Vs(t) and the output voltage V L (t) and state which diodes are on and which are off in the appropriate cycles of Vs(t). Use the offset diode model with an offset voltage of 0.6V. b. Suppose R L = 1000 Ω and a capacitor is added across R L to provide some filtering. Sketch the output voltage V L (t) if the capacitor has a value of 8 μ F. c. Repeat part (b) for a capacitor value of 100 μ F....
