A Buck-boost converter has an output voltage 100 V, output power 60 W and input voltage 12 V. Switching frequency is 15 kHz. Calculate duty ratios for the switch and the diode. Find values for the inductor L and capacitor C, when the allowed output voltage ripple is ±0.15 % and the inductor current ripple is ±1 % (of the average value). If the on-time of the switch has an inaccuracy of ±50 ns, what is the new output voltage...
