Power electronic circuit for hybrid drive train of hybrid vehicle, has insulation layer provided between rail elements and third rail element and representing dielectric of capacitor of circuit capacitor device

摘要

The circuit (1) has power electronic modules (3) arranged at a carrier element (2) and electrically coupled with each other. A rail element arrangement (5) has electrically conductive flat band-like rail elements arranged in parallel in an axial direction. The rail elements are connected with a positive pole and a negative pole of a voltage source and the modules, respectively. An insulation layer is provided between the rail elements and a third electrically conductive flat band-like rail element (10) and represents dielectric of a capacitor of an intermediate circuit capacitor device. Contact elements made of copper wire are connected with the positive pole and the negative pole of the modules.
