Abstract:
The invention relates to a circuit arrangement, comprising at least one wiring carrier plate (1), characterized by at least one separating element (2) formed in the wiring carrier plate (1), which separating element divides the wiring carrier plate (1) into sections separated by the separating element (2), wherein the transfer of vibrations from one section to another section is at least partially decoupled and/or damped by the separating element (2). 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 (3) arranged on the wiring carrier plate (1), and power semiconductors (6).
