Values of Vg = 125 V, V0 = 75 V, f = 15 kHz, R = 10 are given for the buck converter. The switch, diode, coil and capacitor used are considered ideal. According to this: a) In order that the peak-to-peak value of the coil current ripple does not exceed 5% of the rated load current value the inductance (L) of the coil to be used and the average output voltage of the output voltage ripple. Calculate the capacity (C) of the capacitor that should be used to be 1% of the value. b) This circuit must be used for continuous transmission (CCM) operation at 50% load. Find the minimum inductance value.
