Abstract
In order to achieve small noise and small vibration, as well as a small size and a low cost in a power converter including a capacitor module, there is provided a power converter including a power module and a capacitor module. The capacitor module includes: a plurality of capacitor elements each having a flat wound surface; an exterior case; a resin filler; and a restraint point. The exterior case has arranged therein an inclusion serving as a beam in a direction orthogonal to a flat wound surface of at least one capacitor element of the plurality of capacitor elements, and the at least one capacitor element, and the restraint point is arranged substantially in front of the flat wound surface via the inclusion.

A power converter, comprising:
- a power module including a switching element configured to perform power conversion;
- and
- a capacitor module including a smoothing capacitor configured to suppress variation of a power supply voltage supplied to the power module,
- wherein the smoothing capacitor is formed of a plurality of capacitor elements each having a flat wound surface formed by winding a metalized film in a flat shape,
- wherein the capacitor module further includes:
- an exterior case configured to accommodate the plurality of capacitor elements inside of the exterior case;
- a resin filler with which a periphery of the plurality of capacitors is filled in the exterior case;
- and
- a restraint point between the capacitor module and the power converter,
- wherein the exterior case has arranged therein an inclusion serving as a beam in a direction orthogonal to a flat wound surface of at least one capacitor element of the plurality of capacitor elements, and the at least one capacitor element, and
- wherein the restraint point is arranged substantially in front of the flat wound surface via the inclusion.
