Question

Please, need help to do this. the mode is DCM mode.

Problem 2.1 Sketch the current and voltage waveforms of: the inductor current ((t)), the inductor voltage (v(t)) the input current (is(t)), the output diode current (ip2(t)), and the output capacitor current (ico(t)), for at least one full period T when the Buck-Boost converter is operating in Discontinuous conduction Mode (DCM). Assume that the converter is lossless, or 100% efficient, that is: The switch ON-resistance is on, and both the diodes forward voltage drop is zero (VOv) sure to indicate the values of all A template is provided below. Be tudes and heights on the y-axis of your sketches. iL(t) L-Max OA 2T VI (1) is(t) ip2(t) ↑ ico(t) D2 01 D1 Vsw V swi Vs 0 Figure 2.2 Non-inverting Buck-Boost during inductor charging period (D × T).
