Part 1) Consider a step down converter with a resistive load. It is supplied by a DC power source of magnitude Vs = 160 V. The switching period is 0.25 ms and the duty cycle k is first set to 0.5. The load is resistive with R=10 Ohms. The critical value of L and the critical value of C are equal to: a. 0.625mH and 0.392uF b. 0.625mH and 0.196uF c. 0.312mH and 0.196uF d. None of these Part2) Now consider the same given but the load is an inductive load with R=10 Ohms and L=10 mH. The switch is ideal. Calculate The RMS load current Io and the RMS converter current Ir are equal to: Select one: a. 5A and 3.54A b. None of these c. 8A and 5.66A d. 12.5A and 8.84A
