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: An inner core portion includes an inner gap having a length in the first direction larger than that of the outer gap in a center in the first direction. A control device is configured to switch between a one-phase operation of causing a current to flow through any one of the first outer coil, the second outer coil, and the inner coil to operate, a two-phase operation of causing a current to flow through any two of the first outer coil, the second outer coil, and the inner coil to operate, and a three-phase operation of causing a current to flow through all of the first outer coil, the second outer coil, and the inner coil to operate. The control device selects the inner coil in the one-phase operation.

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.

Abstract: The objective is to adjust the magnetic resistance at each coil mounting part to the desired level. The inductor includes a core and coils. The core includes the coil mounting parts extending in the Y direction and arranged in the X direction. The coils are externally fitted around each coil mounting part. The positions of the end faces on the Z− direction side of the coil mounting parts are aligned in the Z direction. The position of the end face on the Z+ direction side of at least a predetermined coil mounting part and the position of the end face on the Z+ direction side of another coil mounting part are different from each other in the Z direction. The cross-sectional area of the predetermined coil mounting part and the cross-sectional area of another coil mounting part are different from each other when viewed in the Y direction.

Abstract: An object is to separately measure the DC and AC components included in a measurement target current. The current measurement device includes a core, a coil, an element, an AC measurement circuit, a low-pass filter, a current adjustment circuit, and a DC measurement circuit. The core allows magnetic flux to flow therethrough due to the measurement target current. The element generates a feedback voltage, based on the magnetic flux flowing along the core. The AC measurement circuit measures the AC component of the measurement target current, based on the feedback voltage. The current adjustment circuit allows a feedback current to flow through the coil, counteracting the DC component of the core magnetic flux, based on the feedback voltage from which the AC component has been removed by the low-pass filter. The DC measurement circuit measures the DC component of the measurement target current, based on the feedback current.
