GATE Electrical Engineering (EE) 2016 Shift 1 Solved Paper

A buck converter, as shown in Figure (a) below, is working in steady state. The output voltage and the inductor current can be assumed to be ripple free. Figure (b) shows the inductor voltage ${\mathit{V}}_{\mathit{L}}$ during a complete switching interval. Assuming all devices are ideal, the duty cycle of the buck converter is ________.
