Answer :
Final answer:
The switched model for the described behavior with switch H and a diode corresponds to a Buck-Boost Converter, which can both step-up or step-down the input voltage. So the correct answer is option A.
Explanation:
To find the switched model of the given DC/DC converter, we need to understand the behavior of the converter when the switch is in position u=1 and when it is in position u=0. During u=1, the switch H is on, and the diode is off which represents the energy storage phase for the inductor. On the other hand, for u=0, the switch H is off and the diode is on, allowing the inductor to discharge its energy to the load and capacitor.
The correct switched model for the described behavior corresponds to a Buck-Boost Converter. This type of converter can step-up or step-down the input voltage based on the duty cycle of the switch. During the on-phase (H on, diode off), the inductor stores energy, and during the off-phase (H off, diode on), it releases the energy to the output side, thus both stepping up or down the output voltage as needed.
