Abstract
Described herein is a multi-level power convertor and a method for a multi-level power convertor. The multi-level power convertor includes a DC port; an AC port; a first power converting unit, a second power converting unit, a coupling inductor, and an inductive filtering unit. The first power converting unit is coupled to the DC port and includes a first AC terminal adapted to provide a first plurality of voltage levels. The second power converting unit is coupled to the DC port and includes a second AC terminal adapted to provide a second plurality of voltage levels, where the second plurality of voltage levels are phase-shifted by 90 degrees with respect to the first plurality of voltage levels. The coupling inductor includes first and second windings with a same number of turns. The inductive filtering unit is arranged between the AC port and ends of the first and second windings.
