Problem 3: The DC-DC Buck Converters are widely used in electric vehicles to charge low-voltage battery and power the onboard electric devices. By knowing the measurement of variables (switch gate signal, inductor voltage VL, and inductor current ripple iL,ripple) as plotted in Fig. 3, calculate the followings: (a) The value of output voltage $\mathrm{Vo}$, (b) The value of input voltage ${\mathrm{V}}_{\text{in, }}$ (c) Duty cycle D of this converter, (d) Draw the inductor current waveform and indicate Max iL and Min iL on the waveform. (Note: the average inductor current is equal to load current of $1.167\mathrm{A}$ for this converter.) (e) The rating of the switch $S$ and diode $D$ Figure 3
