The rectifi er-capacitor circuit of Fig. P1.86b is driven by the asymmetric triangular input of Fig. P1.86a and drives a load that has been modeled with a Norton equivalent. The input wave has Vm 5 10 V, and the load has IL 5 10 mA and RL 5 1 kV. (a) Assuming VD(on) 5 0.7 V, specify C for a 0.5-V output ripple. (b) Sketch and label, versus time, both vO and the diode current iD (sketch vO on the same time diagram as vI ). (c) Find VO, iD(max), iD(avg), TON, and PIV. Warning: the equations of the text, derived for the case of a sinusoidal input and a purely resistive load, do not apply to the present case. You need to develop your own through simple reasoning.
