Abstract
An exemplary system includes an inverter coupled to a DC source, eight power switches and three DC-link capacitors that synthesize seven output voltage levels. In one example the inverter includes a four-level active neutral pointed clamped inverter (4L-ANCP) that includes six power switches of the eight power switches is operated at a switching frequency with a first voltage stress level, and a half-bridge that includes the other two of the eight power switches is coupled to the 4L-ANCP and operated at a fundamental frequency with a second voltage stress, the second voltage stress being higher than the first voltage stress level.
