Abstract :
This paper deals with a new topology for a multi - level - converter without a multi - winding input transformer. By means of this topology, converter with an increased number of voltage steps can be easily realised. The number of valves is smaller than that of actual techniques. Additionally the paper compares the multi - level - PWM with the optimised pulse sequences.
