The invention relates to a circuit arrangement, comprising at least one wiring carrier plate (), characterized by at least one separating element () formed in the wiring carrier plate (), which separating element divides the wiring carrier plate () into sections separated by the separating element (), wherein the transfer of vibrations from one section to another section is at least partially decoupled and/or damped by the separating element (). The invention further relates to a converter having such a circuit arrangement, and to an aircraft having a converter. The converter can comprise capacitor stacks () arranged on the wiring carrier plate (), and power semiconductors ().

Vibration-damped circuit arrangement, converter, and aircraft having such an arrangement

Various embodiments include a capacitor structure comprising: a plurality of capacitors disposed in a support structure, wherein each of the plurality of capacitors includes a first capacitor electrode and a second capacitor electrode. The support structure includes a first electrode and a second electrode. Each of the plurality of capacitors makes electrical contact with the first electrode via the respective first capacitor electrode and with the second electrode via the respective second capacitor electrode. The support structure includes a mounting side for surface mounting, the mounting side comprising a first contact area of the first electrode and a second contact area of the second electrode. The support structure defines a cuboid interior and the capacitors are disposed in the cuboid interior. An outer side of the support structure defines an additional structural framework outside the mounting side.

Capacitor structure and power module having a power electronic component

Various embodiments of the teachings herein include power electronic circuits comprising: interconnected power modules, each with a power electronic element and a plurality of capacitors in parallel. The power electronic elements are mounted on a first side of substrate plates. The capacitors are mounted in a plurality of planes one above the other on a second side of the substrate plates. The substrate plates, with the power electronic elements forward and alongside each other, are fixed onto an assembly side of a base circuit carrier.
