Question

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 $0.2 ms$ and $S2$ is turned on for $0.3 ms$ in a $0.5 ms$ switching cycle time period. Assuming continuous conduction of the inductor current and negligible ripple on the capacitor voltage, the output voltage $V_{0}$ (in Volt) across $R_{L}$ is _______.
