Beschreibung
Zusammenfassung:	An electrical power converting device includes: a converter circuit part that includes a switching circuit and a transformer and converts a voltage between a voltage on a high voltage power source side and a voltage on a low voltage power source side in an unidirectional or bidirectional manner; a filter circuit part that is connected to a low-voltage side of the converter circuit part and includes an inductor and a capacitor; a control circuit board on which a control part is mounted, the control part controlling the switching circuit; and a metal housing in which an interior space of the housing is divided into a first accommodation space and a second accommodation space by a partition wall including a cooling liquid flow path, wherein the converter circuit part is arranged in the first accommodation space, and the filter circuit and the control circuit board are arranged in the second accommodation space.
