Abstract: A bus bar arrangement including two or more bus bars arranged for conducting currents, wherein the two or more busbars are arranged parallel and at a distance from each other, the arrangement including a magnetic structure which is arranged between two bus bars which are next to each other.

Abstract: A power converter arrangement includes a semiconductor switch system with a controllable switch. A capacitor unit includes a capacitor having a capacitance value, the capacitor unit being operatively connected to the semiconductor switch system. A conductor arrangement includes a conductor adapted to conduct an electric current between the capacitor unit and the semiconductor switch system. The conductor has a resistance and an inductance. A resonant circuit is formed by the resistance, the inductance and the capacitance, and the power converter arrangement includes at least one attenuating element for attenuating an electrical ringing in the resonant circuit. The attenuating element is conductively isolated from the resonant circuit. The attenuating element includes ferromagnetic material, and the attenuating element is magnetically coupled to the conductor such that variations in the electric current intensity of the conductor induces eddy currents within the attenuating element.

Abstract: A current conductor structure with a frequency-dependent resistance. The current conductor structure comprises a first current conductor and a second current conductor connected in parallel. The first and second current conductor are configured such that the second current conductor has a higher resistance and a lower inductance than the first conductor so that, above a set frequency limit, the resistance component of a total impedance of the current conductor structure is larger than the resistance component of the impedance of the first conductor current.

Abstract: The present invention relates to a choke (1) of an electrical device, comprising at least one conductor (2, 3) wound into a coil having separate turns of the conductor wound on top of one another, and a cooling element (4) for cooling the choke. In order to achieve efficient cooling without electrical properties of the choke being impaired, the cooling element (4) is arranged against the coil to cool the conductor (2, 3), wound into a coil, of the choke by means of a medium flowing in a direction parallel to the conductor (2, 3) through a cooling channel provided in the cooling element.
