4.5° Consider the two closed-loop controlled converters shown in Fig. P4.5 and answer the questions. 10V L m ID 0.02 ? il L m ip + 10V 1? ?? 8 14 0.02 ?? ? + 1?F 1?F 10?? 10?? Ucon Ucon PWM PWM 16V 2V10?? OV 100 ?? Converter A 2V90 ?? 6V OV 100 ?? Converter B Fig. P4.5 a) For Converter A, determine the value of the inductance L so that the converter operates at the CCM/DCM borderline. You are not allowed to use the formula for the $L_{crit}$ expression. b) Assume that Converter A operates with the inductance L found in a). Under this condition, sketch the inductor current $i_L$, diode current $i_D$, control voltage $v_{con}$, and the ripple component of the output voltage, $v_o = v_o - V_o$, for the two operational periods. Show the maximum and minimum values. c) Repeat a) and b) for Converter B.
