Question:
(a) The piecewise linear approximation given in Figure is assumed for the diode in the circuit shown in Figure. Evaluate the diode current ID.
(b) The piecewise linear approximation given in Figure Q1b2 is assumed for the diode in the battery charger circuit shown in Figure. Sketch the voltage and current waveforms vs(t) and id(t) when the input voltage vs(t)/V is given by vs(t) = 9sinωt. Annotate your sketches.
Consider that the threshold voltage Vo = 0.7 V.
(c) Evaluate the value of RL in the battery charger circuit shown in Figure which will limit the maximum diode current to 100 mA.
