Q4. A boost regulator has an input voltage of 5 V. The average output voltage is 15 V and the average load current is 0.5 A. The switching frequency is 25 kHz. If L=150 μH and C=220 μF, determine
(a) the duty cycle
(b) the ripple current of inductor
(c) the peak current of inductor
(d) the ripple voltage of filter capacitor and
(e) the critical values of L and C. [5]
