Q5 [30 marks] In a step-up converter, Vd = 12 V, Vo = 24 V, Io = 0.6 A, Ls = 150 µH, C = 470µF, and fs=20 kHz.

[8 marks] Plot the iL and υL for a period of Ts showing clearly the values of iLpeak, and υL. Assume boundary operation.









[5 marks] Find the output power po. and the load resistance.












[7 marks] Does the converter works in continuous or discontinuous mode.












[5 marks] Calculate Lmin that will make/keep the converter operating in a continuous-conduction mode.









[5 marks] Calculate ∆Vo /Vo (peak-peak).
