Abstract
A method controls a converter having a plurality of switching modules. Each of the switching modules has controllably interruptible semiconductor switches and an energy store. A switching frequency of the switching modules is regulated in consideration of at least one integral limiting value, wherein the at least one integral limiting value is variably determined over time, in accordance with the energy store voltages of the switching modules.
