Abstract
A potential equalization system for a modular multi-level converter. The converter has a plurality of converter modules and each of the modules has a direct current source. The potential equalization system includes pole contacts, which are each electrically connected to one pole of a direct current source, and at least one electrically conductive contacting element, which can be moved between a first end position in which the contacting element is electrically isolated from the converter modules and a second end position in which the contacting element contacts pole contacts of different direct current sources and can be put on ground potential.
