Abstract

The present disclosure relates to converter modules. The teachings thereof may be embodied in converter modules for a multi-level energy converter. For example, a method for operating a converter module of a multi-level energy converter by means of a control unit and via a control connection may include: controlling the switching states of one of two converter module connections of the converter module and a switching unit incorporating the control connection. Two series-connected converter module capacitors connected to the switching unit respectively deliver a converter module capacitor voltage. The switching unit switches the converter module capacitor voltage of one of the converter module capacitors or a summed voltage of the series-connected converter module capacitors to the converter module connections, according to the respective switching state of the switching unit.
