  • Publication number: 20240097566
    Abstract: A DC-DC converter, a vehicle including the converter, and a controlling method thereof are provided. The DC-DC converter includes a first capacitor connected to a first DC terminal, a second capacitor connected to a second DC terminal, a plurality of converting circuits each including at least an inductor and a plurality of switching elements, and connected to each other in parallel between the first capacitor and the second capacitor, and a controller configured to control an ON/OFF state of the plurality of switching elements provided of each of the converting circuits. When external power connection with respect to each of the first DC terminal and the second DC terminal is disconnected, the controller is configured to control states of the plurality of switching elements to sequentially provide a plurality of different discharge paths between opposite terminals of the second capacitor via the plurality of converting circuits.

  • Publication number: 20240092187
    Abstract: A direct current to direct current (DC-DC) converter, a vehicle including the converter, and a controlling method thereof are proposed. The DC-DC converter is capable of efficiently detecting and responding to miscoupling of a connector. The DC-DC converter includes a first inlet corresponding to a first DC terminal, a transformation circuit connected to the first DC terminal and a second DC terminal while being located therebetween, and a converter controller, wherein when receiving a voltage command corresponding to the first DC terminal from an external controller, the converter controller is configured to determine whether or not a connector coupled to the first inlet is miscoupled thereto based on whether or not a voltage of the first DC terminal follows the voltage command.
