Electronic components included in a power conversion unit are housed in a closed section of a first unit, and the first unit includes a heat sink exposed to an open section and releases heat transferred from the electronic components. A blower is housed in a first space of a second unit, and at least a portion of an impeller of the blower is exposed to a second space from an opening. A reactor is housed in a third unit. Outside air flows through a flow inlet into an interior of the power conversion device, passes through the open section, a first vent, the second space, the opening, the first space, a second vent, and the third unit, and then is discharged to the exterior of the power conversion device from a flow outlet.

Controller for railway vehicle

There is provided a vehicle controller that is mounted in a box-shaped manner beneath the floor or on the roof of a vehicle so as to supply electric power to vehicle apparatuses. The vehicle controller is configured with a plurality of functional modules; each of the functional moduleshas at one side thereof an interface sidein which a first interface regionwhere signal-line terminals are arranged and a second interface regionwhere power-line terminals are arranged are separated; in each of the interface sides, the first interface regionis disposed in the vicinity of one and the same end and the second interface regionis disposed in the vicinity of the other and the same end; the plurality of functional modules includes a monitoring circuit, an overvoltage protection circuit, and an inverter.

Vehicle controller

A vehicle control device includes plural functional modules each of which is a minimum part unit that contributes to change in input/output potentials, and has an input and an output of one power line or one set of power lines, except for power lines having a same potential as that on an overhead wire side or that on a ground side. The functional module has an interface surface on one side surface, to which both of a signal line and the power line are connected. Each interface surface is divided into a first interface area in which a signal line terminal connected to the signal line is placed, and a second interface area in which a power line terminal connected to the power line is placed. The plural functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one end side in common, and the second interface areas are located on the other end side in common.
