Abstract: A modular embedded multi-level converter (MEMC) includes a first phase portion and a second phase portion. The first phase portion includes a first switch stack operable to couple a first phase branch between a positive DC bus and a midpoint node. The second phase portion includes a second switch stack operable to couple a second phase branch between the midpoint node and a negative DC bus. A DC voltage between the positive DC bus and the negative DC bus is distributable among switching units disposed in the first phase branch and the second phase branch. A distribution of the DC voltage is controlled by regulating a DC voltage at the midpoint node to balance energy among the switching units.
