Abstract: Object: To reduce the size of a device. Solution to Problem: A switching module according to one aspect of the present disclosure is a module used in a power conversion circuit. The switching module includes a case member formed to extend in a first direction and a second direction, one or more switching elements disposed to face the case member in a stacking direction orthogonal to the first direction and the second direction, and a pressing member configured to press at least part of the one or more switching elements toward one side in the stacking direction via the case member. The one or more switching elements are disposed closer one end portion of both end portions of the case member in the second direction.

Abstract: A power converter apparatus includes a case, a power converter which is in the case and converts input power to predetermined power and output the predetermined power, a first switch positioned in the case and connected to the converter component, a second switch positioned in the case and connected to the converter component, the second switch having a moving component which moves between first and second positions, and a cover which is installed on the case such that the cover covers the first switch and which moves in two mutually different directions relative to the case such that the cover is removed from the case. The cover has a contact portion which makes contact with the moving component of the second switch in the first position and which restricts movement of the cover in one or more of the two directions when the cover is moved in the two directions.

Abstract: An inverter includes: a housing base which includes a front area and a rear area opposite to the front area; a main body which is arranged in the front area of the housing base and houses a plurality of electronic components forming a power conversion circuit; a first duct which is arranged in the rear area of the housing base and includes a first end connected to an intake port of cooling air; a first heat sink which is arranged in the rear area of the housing base and includes a first fin and a first heat sink base extending perpendicular to an extension direction of the first duct; and a reactor which is arranged in the heat sink base in the rear area of the housing base, and generates heat at the time of energization.
