In a step-up converter, consider all the components to be ideal, Let Va be 8-16 V, V.-24 V (regulated), f.-20 kHZ, Po ≥ 6 W. i). Calculate the minimum inductance L required to keep the converter operation in continuous-conduction mode under all conditions. ii). Specify the value of inductor for a maximum ripple of 3%. iii). Design a capacitor for part (i) and (ii) with a voltage ripple of less than 2%.
