Mechanical arrangement of a multilevel power converter circuit

摘要

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.
