Abstract
A multilevel power converter has at least one phase module with a plurality of modules connected between positive and negative DC voltage connections. The phase module has a first phase module branch connected to the positive DC voltage connection, and a second phase module branch connected to the negative DC voltage connection. Each of the modules has at least two electronic switching elements and an electric energy storage unit. A third phase module branch connects the first phase module branch to the second phase module branch. A switching device connects an AC voltage connection of the multilevel power converter to a first connection node between the first phase module branch and the third phase module branch in a first switch position and connects the AC voltage connection to a second connection node between the third phase module branch and the second phase module branch in a second switch position.
