摘要： A capacitor has a parasitic inductance component and is electrically connected between a positive line and a negative line. A converter includes a reactor provided in the positive line and performs voltage conversion of a DC voltage smoothed by a capacitor. An inverter performs DC-AC conversion between the converter and an AC motor by switching control. A path of the positive line which connects a DC power supply and the capacitor has an inductance smaller than an inductance of a path of the negative line which connects the DC power supply and the capacitor. A difference between the inductance of the path and the inductance of the path is less than twice the parasitic inductance component.

摘要： A power converter includes: a base conductor, an electrically heating member which is provided on the base conductor, a noise reduction capacitor of flat plate-shape in which via an insulator, a plurality of first electrodes and second electrodes are alternately layered, on one surface, the first electrode in an outermost layer is exposed and on another surface, the second electrode in an outermost layer is exposed, a relay conductor which is electrically connected to other members from the electrically heating member via the noise reduction capacitor, and the second electrode in an outermost layer of the noise reduction capacitor is face-joined to a face of the base conductor at a side where the electrically heating member is provided and the first electrode in an outermost layer and the relay conductor are face-joined.
