Abstract:
A multilevel converter has a plurality of series-connected sub modules, which each have at least one first switch, one second switch and one capacitor. Current is output by way of the capacitor during discharging phases and current is received or charging the capacitor during charging phases. At least one of the sub modules has two part-modules that are galvanically connected to each other or are formed by two part-modules that are galvanically connected to each other. Each has a first switch, a second switch and a capacitor, and a first and a second part-module terminal. The galvanic connection between the two part-modules includes at least one inductive element.
