A new Space Vector Modulation Strategy for multilevel inverters

In this paper a new Space Vector Pulse Width Modulation method is proposed for multilevel voltage source inverters. This method is based on Space Vector Modulation and is compared to other similar methods. According to the method presented the multiplicity of the switching states of a multilevel inverter is also considered. This means that the new pulse method takes into account the multiplicity of the switching states which means a symmetrical distress of the inverter´s elements while the number of transitions in a switching time is 7. This method can be applied in a multilevel inverter who feeds a high power three-phase passive load or a high power three-phase motor drive. The new method was used in order to pulse a five-level inverter, which feeds a high power passive load using Matlab-Simulink, and the results are shown in this paper.
