A novel hybrid multiphase multilevel inverter topology

© 2017 EMO (Turkish Chamber of Electrical Enginners). This paper presents a new hybrid multiphase multilevel inverter topology for multiphase systems especially for multiphase machines. The proposed topology is able to generate different voltage levels with less number of power electronic counts. The proposed topology uses unidirectional and bidirectional switches to generate different voltage levels. The common voltage of the proposed topology is zero due to clamping the midpoint of the dc-link multilevel inverter to the ground by bidirectional switches. Fundamental frequency switching is used for triggering the power switches and the results are verified by MATLAB/Simulink software.
