An electric power conversion device of an embodiment includes: a primary side negative electrode terminal; a secondary side negative electrode terminal; a negative electrode terminal of a switching element connected between the primary side negative electrode terminal and the secondary side negative electrode terminal; a first conductive member connected to the primary side negative electrode terminal; a second conductive member connected to the negative electrode terminal of the switching element; and a third conductive member connected to the secondary side negative electrode terminal, wherein the first conductive member, the second conductive member, and the third conductive member are connected to one another, and the first conductive member is formed as a separate body separately from the second conductive member and the third conductive member.

Electric power conversion device

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.

Control device for power conversion device

An electric power conversion device is provided with a case () which includes: a first member () having a first region () defining therein a first passage () in which a cooling medium flows, and a second region () disposed on a side of the first region; and a second member () 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 () connected to the first passage. A reactor () is positioned in the first region, and a switching device () is positioned on the surface of the second member facing away from the first member while a capacitor () is positioned between the second member and the second region of the first member.

An electric power conversion device is provided with a case () including a mounting portion () extending along a plane defined by a first direction and a second direction that are orthogonal to each other, and a side wall () provided along a periphery of the mounting portion, a primary side connection portion () and a secondary side connection portion () provided on the case, a plurality of reactors arranged along the second direction in the case and connected in parallel to one another, and a switching unit including a plurality of switching devices positioned in the case on one side of the reactors in the first direction, arranged along the first direction, and respectively connected to the reactors.
