Abstract

The present invention relates to a method of PWM switching for control for a converter having a plurality of parallel converter legs per phase and a converter having a plurality of parallel converter legs in each phase. The plurality of converter legs may assume a set of possible different switching states, wherein the converter may be exposed to a cyclic load. Furthermore, the present invention relates to a converter having a plurality of parallel converter legs in each phase, wherein the converter includes a control block for identifying different switching states.
