Abstract
A method for operating an N-level K-phase electrical power converter, wherein N is greater than or equal to 3 and K is greater than or equal to 1. The method includes: providing a plurality of N connection points that each correspond to a definable potential, wherein a first connection point corresponds to a first potential, a second connection point corresponds to a second potential, and at least one further connection point corresponds to a further potential which is lower than the first and greater than the second potential; providing a plurality of K output connections that are each selectively connected to a respective one of the connection points via at least one switching device; and having at least one current flowing into the at least one further connection point.
