Question

A boost converter is required to have an output voltage of 8 V and
supply a load current of 1 A. The input voltage varies from 2.7 to
4.2 V. A control circuit adjusts the duty cycle to keep the output
voltage constant. If the switching frequency is 200 kHz,

determine:
i. a value for the inductor such that the variation in inductor
current is no more than 40% of the average inductor current for
all operating conditions.
ii. a value for the capacitor such that the output voltage ripple is
no more than 2%.
iii. in case the OFF period is reduced by 30% for constant
frequency operation, find the new output voltage
