1. A mechanical arrangement of a multilevel power converter circuit for a single phase leg, comprising:
- a first inverter portion including (i) three or more direct current (DC) voltage input ports, and (ii) a first plurality of capacitors electrically coupled to the DC voltage input ports, and (iii) only one alternating current (AC) voltage output port, the first portion corresponding to a first half of the phase leg;
a second inverter portion including (i) the three or more DC voltage input ports, and (ii) a second plurality of capacitors electrically coupled to the DC voltage input ports, and (iii) the one AC voltage output port, the second portion corresponding to the other half of the phase leg;
wherein each capacitor of the first plurality of capacitors forms a parallel capacitor with a corresponding one of the capacitors of the second plurality of capacitors.

Abstract
A mechanical arrangement of a multilevel power converter circuit includes a power converter having a first portion with a plurality of first control inputs, at least three direct current voltage inputs, and an alternating current voltage output, and a second portion with a plurality of second control inputs, the at least three direct current voltage inputs and the alternating current voltage output. The second portion is split apart from the first portion. The power converter has at least three levels corresponding to the at least three direct current voltage inputs.
