The Buck-Boost converter acts as a Buck converter when the duty cycle is less than 0.5. Therefore, the correct answer is d. 0.4.

Here's a step-by-step explanation:

1. A Buck-Boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is equivalent to a flyback converter using a single inductor instead of a transformer.

2. Two different topologies are called buck–boost: the inverting topology and the non-inverting topology.

3. The buck–boost converter is a type of switched-mode power supply that combines principles of the buck converter and the boost converter in a single circuit. Like other SMPS designs, it provides a regulated DC output voltage from either an AC or a DC input.

4. When the duty cycle is less than 0.5, the converter acts as a buck converter, which means it's stepping down the input voltage.

5. When the duty cycle is more than 0.5, it acts as a boost converter, stepping up the input voltage.

6. Therefore, the correct answer is d. 0.4, as it's the only option less than 0.5.
