In a step-down converter, consider all the components to be ideal, Let V. the output voltage is to be held constant at 8 V by controlling the switch duty ratio D.

If V is 10-40 V, Po ≥ 6 w and fₛ=50 KHZ.

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 2%.

Simulate your two designs (i) for the inductor boundary condition operation, (ii) continuous conduction mode of operation and through the computer simulation results prove that your controller and converter design meets the design specifications.
