Design a buck converter to produce an output voltage of 18 v. across a 10 om load resistor. The output voltage ripple must not exceed 0.5% The dc supply is 48 v. and fs=20 KHZ. Design for continuous inductor current. specify the duty ratio (D). the size of the inductor and capacitor. the peak voltage rating of each device. and the rms current in the inductor and capacitor.
