    Abstract: To continuously supply power at a remote location by repeatedly receiving power from a power supply mobile body when supplying power at a remote location away from the charging infrastructure.
    A server in communication with an external power feeder that feeds power to an external load, and a power supply mobile body that has power for supplying to the external power feeder, is configured to: receive a charging request to the external power feeder; acquire a power supply condition in the power supply mobile body including an amount of power that the power supply mobile body can supply to the external power feeder; select a power supply mobile body based on the charging request and the power supply condition; and set a power receiving/supplying schedule based on a required amount of power included in the charging request and the amount of power that the power supply mobile body can supply.

    Abstract: An electric power conversion device is provided with a case (60) which includes: a first member (61) having a first region (73) defining therein a first passage (78, 79) in which a cooling medium flows, and a second region (74) disposed on a side of the first region; and a second member (88) disposed so as to at least partly overlap with the second region as seen from a direction orthogonal to the second region in a spaced apart relationship to the second region, and internally defining a second passage (91) connected to the first passage. A reactor (31) is positioned in the first region, and a switching device (33) is positioned on the surface of the second member facing away from the first member while a capacitor (35) is positioned between the second member and the second region of the first member.

    Abstract: A voltage conversion device can selectively switch between and perform voltage control and current control of a voltage conversion unit in a suitable manner in which output characteristics of a power source are reflected. A control unit (10) of the voltage conversion device (1) selectively switches the control mode of the voltage conversion unit (3) to a current control mode or a voltage control mode on the basis of current-voltage characteristics of the power source (2) and performs a control process of each control mode. The power source (2) has current-voltage characteristics such that the output voltage changes according to the output current and such that a rate of change of the output voltage with respect to a change of the output current changes according to the output current.

    Abstract: A control device, for a power conversion device using a three-phase magnetic coupling reactor, includes: a first outer coil; a second outer coil; an inner coil disposed between the first outer coil and the second outer coil; and a core including a first outer core portion around which the first outer coil is wound, a second outer core portion around which the second outer coil is wound, and an inner core portion around which the inner coil is wound. Directions of magnetic fluxes generated in the first outer coil, the second outer coil, and the inner coil are opposite to each other in any combination. In a three-phase operation, the control device controls a value of the current flowing through the inner coil so as to approach values of the currents flowing through the first outer coil and the second outer coil.
