Abstract
Various embodiments include a coil device for a power converter, the device comprising: a cooling plate; and a plurality N≥3 of coil windings. The cooling plate is thermally coupled to at least one end face of one of the plurality of coil windings. The coil windings are spatially offset from one another by an angle of 2π/N. The cooling plate defines a cooling channel extending at least partially around each of the plurality of coil windings.
