GATE Electrical 2014 Set 1 | Question: 54
Figure $(i)$ shows the circuit diagram of a chopper. The switch $S$ in the circuit in figure $(i)$ is switched such that the voltage $v_D$ across the diode has the wave shape as shown in figure $(ii)$. The capacitance $C$ is large so that ... switch $S$ and the diode are ideal, the peak to peak ripple $(\text{in}\: A)$ in the inductor current is _________.

GATE Electrical 2015 Set 1 | Question: 31
The circuit shown is meant to supply a resistive load $R_{L}$ from two separate $DC$ voltage sources. The switches $S1$ and $S2$ are controlled so that only one of them is $ON$ at any instant. $S1$ is turned on for $0.2 ms$ ... inductor current and negligible ripple on the capacitor voltage, the output voltage $V_{0}$ (in Volt) across $R_{L}$ is _______.
