Q.38. The circuit shown in meant to supply a resistive load from two separate DCvoltage sources. The switches are controlled so that only one of them is ON at any instant. is turned on for 0.2 ms and 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(in Volt) across is______
