Problem 2.2 Using the same methods shown in lecture, mathematically derive: (a) The voltage conversion ratio equationwhen the Buck-Boost is operating in Discontinuous Conduction Mode (DCM). Your answer should be a function of D, Ro, T, and L (b) The value of the inductor discharge duty cycle coefficient; D1.Your answer should be a function of Ro, T, and L. Hint 1: Other than assessing the current waveforms, you will also need to apply the assumption of 100% efficiency from Problem...
