Problem 3: Consider the Chuck regulator in Figure 2. Take Vs=12V & Is= 0.5A. Take L=200µH, C=250µF. The energy transfer Capacitance, C1 is 200µF, and Inductance, L1= 250µH.Compute f) The average output voltage Va, g) The average output current la, h) Peak to peak output voltage ripple of Capacitor C1, AVc1, i) Peak-to-peak ripple current of inductor L1, AI1, j) Peak to peak output voltage ripple of Capacitor C2, AVC2, k) Peak-to-peak ripple current of inductor L2, A12, 1) Peak current of the transistor, Ip. The Consider the following scenarios: 3. K=0.5, The switching frequency is swept from 10KHz to 100KHz with increments of 5Khz 4. K is swept from k=0.1 to 0.9 with 0.05 increments, switching frequency is fixed at 25 KHz .Show the results in tabular form and graph.
