APPARATUS WITH REACTOR

The present invention provides an apparatus for the purpose of reducing vibration of a device provided with a metal material around a reactor. The device includes a control substrate, a reactor electrically connected to the control substrate, a control substrate housing portion that houses the control substrate and the reactor, and a planar portion or a control substrate cover that is formed to besubstantially parallel to the control substrate and includes a metal material. In this device, the leakage magnetic flux generated by the current flowing through the reactor is anisotropic, and the reactor is disposed such that the direction in which the planar portion or the control substrate cover is located becomes a direction in which the leakage magnetic flux is small. 本发明提供种设备，的目的在于减少在电抗器周围设有金属材料的设备的振动。设备具有控制基板、与控制基板电连接的电抗器、收纳控制基板和电抗器的控制基板收纳部、以及设为与控制基板大致平行且含有金属材料而形成的平面部或者控制基板罩，该设备中，电流在电抗器流动而产生的漏磁通量存在各向异性，以使平面部或者控制基板罩所处的方向成为漏磁通量较少的方向的方式配置电抗器。
