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.
