Question

Pb 1. A boost regulator has an input voltage of 5 V, an average output voltage of 15 V, and an average load current of 0.5 A. The switching frequency is 25 kHz. If the boost inductor is 150 µH and the output capacitor is 220 µF, then determine the following design parameters: • Steady state duty cycle • The ripple current of the inductor • The peak current of the boost inductor • The ripple voltage of the output capacitor • The critical values of the boost inductor and the output capacitor.

Step 1

Determining the steady state duty cycle: The ripple current of the inductor is IRL = 150 uH * 25 kHz = 3.75 A. The peak current of the boost inductor is IMAX = IRL * (1 – duty cycle) = 3.75 A * (100 % – duty cycle) = 4.75 A. The ripple voltage of the output Show more…
