Abstract: Inverter apparatuses and systems with a DC energy source are disclosed, in which a planar and radially symmetrical positive DC busbar is coupled with a positive terminal of the DC energy source and a planar and radially symmetrical negative DC busbar is coupled with a negative terminal of the DC energy source. The inverter has a plurality of switches such that the plurality of switches are positioned radially symmetrically with respect to a center of the DC busbars. Each switch is coupled with either the positive DC busbar or the negative DC busbar on a first end and one of a plurality of AC busbars on a second end. A single toroidal filtering core is located at the center of the DC busbars and is coupled with the plurality of AC busbars.

Abstract: Disclosed are designs for inductor cores for electromagnetic interference (EMI) filters. In some embodiments, an inductor core comprises a plurality of enclosed structures, where each enclosed structure of the plurality of enclosed structures includes a plurality of elongated bars and at least one connection device. In some embodiments, an enclosed structure is configured to encompass a signal bus. In some embodiments, an enclosed structure has a longitudinal axis and a triangular cross-sectional shape taken perpendicular to the longitudinal axis.
