Abstract
A power electronics device for controlling an electric machine, for example a permanently excited synchronous machine includes a plurality of capacitors and power semiconductors connected to a bus bar. To measure currents through the bus bar, the bus bar includes at least one portion with a shaped section. This at least one portion comprises an essentially U-shaped configuration. A sensor of a current-measuring device is provided in the vicinity of the at least one portion to measure the current flowing therethrough. The sensor is designed to measure an electric and/or magnetic field in the bus bar and is in turn connected to an evaluation device. The sensor and/or the evaluation device are disposed on at least one control printed circuit board of the power electronics device, which is arranged underneath the bus bar.
