GATE Electrical Engineering (EE) 2014 Shift 1 Solved Paper

Figure (i) shows the circuit diagram of a chopper. The switch s in the circuit in the figure (i) is switched such that the voltage V_D across the diode has the waveshape as shown in the figure (ii). The capacitance C is large so that the voltage across it is constant. If the switch s and diode d are ideal
The peak to peak ripple (in A) in the inductor current is-
