6. 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
