Abstract: A current measuring device in a power electronics system includes at least one circuit board and an electrical conductor which is guided through a frame surrounding the circuit board. The current measuring device includes a soft magnetic core surrounding the insulation of the electrical conductor, which core is arranged in the frame. The soft magnetic core is open at one location. A magnetically sensitive sensor, in particular a Hall sensor, is arranged in the recess of the soft magnetic core surrounding the insulation of the electrical conductor in order to detect the magnetic field strength.

Abstract: A power electronics module includes a capacitor having a trough-shaped housing and at least one capacitor winding. An electronic unit includes a base on which the capacitor is mounted. A cooling plate in thermal contact with a cooling surface of the capacitor is formed by a bus bar. The cooling plate is on the base of the electronic unit.

Abstract: A vehicle has a power supply device (1) for an electric motor (7) and a method provides for supplying power to the electric motor (7). Another method produces an intermediate storage device (9) for the vehicle power supply device (1). The vehicle additionally has a vehicle battery (8), the intermediate storage device (9), and a converter (10) for supplying power to the electric motor (7). The intermediate storage device (9) is arranged between the vehicle battery (8) and the converter (10). The intermediate storage device (9) has an intermediate storage module (11) having an integrated discharge device (12), wherein the discharge device (12) converts the stored electric energy into heat energy upon discharging the intermediate storage device (9).
