In a Boost converter of Fig. (a & b), the inductor current has ?iL=2 A. It is operating in dc steady state under the following conditions: Vin=5V, V0=12V, P0=10W, and fs=200kHz.

(a) Assuming ideal components, calculate L.

(b) Draw the waveforms for vA, vL, iL,ripple, iL, idiode, iC, considering the duty cycle waveform shown in Fig.?

(c). Indicate clearly all the values in the graph and give the necessary calculations wherever, necessary.
