Abstract
A method for operating a power converter is described. The power converter includes three input nodes each configured to receive a respective one of three input voltages, two DC link nodes configured to provide a DC link voltage, and a midpoint coupled to each DC link node. Three inductors are each connected to a respective one of the three input nodes. A rectifier bridge including three bridge legs are each coupled to a respective one of the three inputs through a respective one of the three inductors and connected to the respective one of the three inductors at a respective switch node. Each bridge leg is connected to the two DC link nodes and the midpoint, and includes at least one electronic switch. The power converter is operated in a reduced switching mode by deactivating at least one of the three bridge legs for a predefined time period.
