I’m trying to study for my Engineering course and I need some help to understand this question.
- A buck-boost regulator has an input voltage of Vs = 15v. The duty cycle, k = 0.4 and the switching frequency is 20kHz. The inductance, L= 200µH and filter capacitance, C= 250µF. The average load current, Ia = 1.75A. Determine the;
- Average output voltage, Va
- Peak-to-peak output voltage ripple, ΔVc
- Peak-to-peak ripple current of inductor, ΔI
- Peak current of the transistor, Ip
