The arrangement relates to a voltage transformer for transformation between a direct voltage at a direct voltage gate and a single-phase or multi-phase alternating voltage at an alternating voltage gate by temporal clocking of an electronic switching unit, via which each phase of the alternating voltage gate can be connected either to a positive pole or to a negative pole of the direct voltage gate. The positive pole and/or the negative pole of the direct voltage gate is connected via at least one capacitor to a ground connection. The ground connection can be connected to an external ground, and the connection between the capacitor and the ground connection is guided via at least one switch element. The arrangement also relates to a motor vehicle having the electric powertrain. A diagnosis arrangement includes a voltage source and monitors the state and function of a switching element.

Embodiments relate to a control device for an electric motor having at least one phase. The control device includes a power unit having a first switching element and a first flyback element corresponding to the first switching element and a second switching element and a second flyback element corresponding to the second switching element. The first switching element is designed to couple a corresponding power connection of the motor with a positive supply voltage. The second switching element is designed to couple the corresponding power connection of the motor with a negative supply voltage; and a control unit designed to separately detect a first current flowing through the first switching element or second switching element corresponding to the phase, to detect a second current flowing through the flyback element corresponding to the respective second switching element or first switching element, and to control the switching elements of the power unit.

A method for activating a safety actuator of a motor vehicle includes: ascertaining an endangerment model of the motor vehicle with the aid of an anticipatory sensor system and at least one characteristic value of a pose of a driver of the motor vehicle; ascertaining a controllability of the motor vehicle by a driver of the motor vehicle with the aid of the at least one characteristic value; and activating the safety actuator to an extent which is a function of the endangerment model and the controllability.

A method and a control device for triggering passenger protection devices for a vehicle are provided, a rollover event causing the triggering of the passenger protection devices. The rollover event is detected as a function of kinematic and rotation variables, an adhesion, and a static stability factor. A state of rotation is ascertained via a rotation rate and a rotation angle. A state of adhesion is ascertained from a vehicle transverse acceleration and a vehicle vertical acceleration. The rollover event is detected via the state of adhesion and the state of rotation, the adhesion being much greater than the static stability factor.
