Performance Investigation of Hexagram Inverter for High Power Applications

This paper presents the performance investigation of Hexagram Inverter for high power applications. It can be used for 3-phase and 6-phase applications. It has many advantages such as less number of switches, easy construction and maintenance, isolated dc buses. Further, due to the module interconnection it has built-in fault tolerant feature. Compared to cascaded H-bridge inverter, it requires low dc energy storage. This well-known quality makes the system in high power applications. Hexagram inverter fed three phase induction motor drive is developed in Matlab/Simulink environment. Simulation is carried out to study the performance of the 3-phase induction motor at different load conditions and the results are presented.
