Abstract: The invention relates to a method (400) for regulating an electric machine (190), comprising a harmonic filter (150), said harmonic filter (150) comprising a second filter (142) and a filter output transformer (132). The method has the steps of: ascertaining (410) a feedback variable (Idq); determining (414) a filter specification variable (FV); filtering (415) the filter specification variable (FV); ascertaining (417) a filtered feedback variable without harmonic components (IdqFunda); and energizing (480) at least one winding of the electric machine (190) on the basis of the filtered feedback variable without harmonic components (IdqFunda).

Abstract: The invention relates to an electric servo drive (10) for a motor vehicle, comprising an actuator (13) for at least indirectly moving an element (14) of the electric servo drive (10). According to the invention, the electric servo drive (10) additionally comprises at least one sensor element (15) which is designed to sense a measured variable that is not used for moving or actuating the element (14) of the actuator (13).

Abstract: In a method for current measurement in a multiphase current network, a conductive connection is produced between a plurality of the phases of the multiphase current network such that the plurality of the phases is short-circuited with one another. At a detection time, a current value flowing between the conductive connection and a first voltage potential is detected.

Abstract: A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it. To that end, it is proposed in particular that at the or each star point, an additional series resistor, frequency-dependent for frequencies below 100 MHz, be disposed in the incoming supply line branches. The series resistor is preferably configured as a ferrite sleeve.
