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.
