Bidirectional DC-DC converter, traffic system, control method, and non-transitory computer-readable storage medium

A control method to be executed by a bidirectional DC-DC converter,

• the bidirectional DC-DC converter that includes
• a first circuit that is configured to process a first voltage being a DC voltage and that includes a first electronic component including a first switching element,
• a second circuit that is configured to process a second voltage or a third voltage, the second voltage being a DC voltage supplied to an electric vehicle, the third voltage being a DC voltage generated in an electric vehicle, and that includes a second electric component with a lower withstand voltage than the first electronic component, the second electric component including a second switching element,
• at least one rotation sensor that is configured to detect a number of rotations of wheels per unit time, the wheels being provided with the electric vehicle, and
• a control circuit,
• the method comprising:
• acquiring a detection result of the number of rotations of the wheels from the at least one rotation sensor;
• determining an idling of the wheels from the detection result;
• controlling switching of at least one of the first switching element and the second switching element;
• in a case of controlling the switching of the first switching element, controlling the switching of the first switching element based on a result of the determination;
• and
• converting the first voltage into the second voltage or converting the third voltage into the first voltage.
