摘要： A power electronics unit (1) for an electric drive unit, having an electrically conductive carrier element (2) and a power semiconductor module (3) arranged on the carrier element (2). The power semiconductor module (3) is designed to convert a direct current into a three-phase alternating current, and a current sensor (4) used to determine the alternating current is integrated such that it forms a main module (5) with the carrier element (2) and the power semiconductor module (3). A drive train for a motor vehicle having such a power electronics unit (1) is also provided.

摘要： A method is provided for ascertaining a rotary position of a rotor, which is assigned to an electric motor and which is able to rotate about an axis of rotation with respect to a stator and the rotary position of which is ascertained by at least one measurement value of a rotary sensor by virtue of at least one measurement value of the rotary sensor being compared at a first time during operation of the rotor with a stored sensor measurement value reference. The method includes calculating the rotary position present at the rotor at the first time based on a comparison between a sequence of measurement values and a sequence of reference values. The stored sensor measurement value reference includes the sequence of reference values, and the reference values are previously stored measurement values of the rotary sensor at various rotary positions of the rotary sensor. The measurement values recorded before the first time are stored as the sequence of measurement values.
