Question
The circuit shown is meant to supply a resistive load 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 and S2 is turned on for in a 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 ________.
Correct answer
7 to 7
Solution
In steady state, the average voltage across the inductor is zero. The voltage at the input of the filter, , alternates between the two source voltages depending on which switch is ON.
