1. A filter of DC voltage (U) for an inverter input of an electric machine for propelling an aircraft, comprising:
a positive busbar and a negative busbar; and
differential mode capacitors (Cdm) connected between two respective portions of the positive busbar and the negative busbar;
wherein each of the two portions each have parallel folds so as to define at least three planes following one another and inclined with respect to one another, one of the two portions being an internal portion and the other of the two portions being an external portion, the internal portion being nested in the external portion so that each plane of one of the two portions extends parallel opposite an associated plane of the other of the two portions.
