The circuit shown in meant to supply a resistive load R L from two separate DC voltage sources. The switches S 1 and S 2 are controlled so that only one of them is ON at any instant S 1 is turned on for 0.2 ms ad S 2 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 O (in volt) across R L is –

The circuit shown in 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 ad 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_O (in volt) across R_L is –
