Power converter designed to minimize mechanical vibration of converter component
First Claim
1. A power converter comprising:
- a converter casing which is made of an assembly of a first case body and a second case body and has a storage chamber defined therein, the first case body including a bottom plate, the second case body including a top plate which faces the bottom plate, at least one of the first case body and the second case body having side plates which extend from a corresponding one of the bottom plate and the top plate to the other;
a capacitor which is secured to the bottom plate within the storage chamber of the converter casing, the capacitor including a capacitor casing and a capacitor device which is disposed within the capacitor casing and sealed with potting resin so as to have a potting surface through which the potting resin is exposed outside the capacitor casing, the capacitor being fixed on the bottom plate with the potting surface oriented perpendicular to a normal direction of the bottom plate; and
a connector which mechanically connects the bottom plate of the first case body and the top plate of the second case body and is located away from the side plates.

Abstract
A power converter includes a converter casing made of an assembly of a first case body and a second case body. The first case body has a bottom plate. The second case body has a top plate. Side plates are arranged between the top plate and the bottom plate. A capacitor is disposed in the converter casing and includes a capacitor casing and a capacitor device which is sealed with potting resin so as to have a potting surface through which the potting resin is exposed outside the capacitor casing. The capacitor is fixed on the bottom plate with the potting surface oriented perpendicular to a normal direction of the bottom plate. A connector is provided which mechanically connects the bottom plate and the top plate and is located away from the side plates, thereby enhancing the suppression of mechanical vibration of the capacitor on the bottom plate.
