Abstract
The invention relates to an attenuation element. According to the invention, this attenuation element has two rail pieces (46, 48) and two conducting pieces (50, 52), wherein a rail piece (46, 48) and a conducting piece (50, 52) each are electrically connected in parallel, wherein these rail pieces (46, 48) are spatially disposed in parallel at a distance from each other, and wherein the conducting pieces (50, 52) each are made of electrically highly conductive material, and the rail pieces (46, 48) each are made of an electrically poorly conductive material. In this manner, the high-frequency currents can be substantially attenuated in a rectifier having distributed intermediate voltage circuits without the power loss in the intermediate voltage circuit markedly increasing such that the capacitors (10, 12, 24, 28) of the rectifier having distributed intermediate voltage circuits no longer need to be oversized with regard to an RMS current of the intermediate voltage circuit of this rectifier.
