Problem 2: Consider the Buck-Boost regulator in Figure 2. Take Vs=12V & Is= 0.5A. Take L=200µH, C= 250µF. Compute a) The average output voltage Va, b) The average output current la, c) Peak to eak output voltage ripple, AVC, d) Peak-to-peak ripple current of inductor, Al, Peak current of the transistor, Ip. The Consider the following scenarios: 1. K=0.5, The switching frequency is swept from 10KHz to 100KHz with increments of 5Khz 2. 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.
