Abstract

A six phase system is a balanced multiphase system that can be replace, in certain applications, the three phase system and the application becomes much fault tolerant. In the six phase system a phase angle of 60 degrees is maintained between the phases. Handling power with more number of phases reduces the maximum current in each of the phase in the system. In this work a six phase balanced AC output is derived from a three phase AC source. The proposed system uses a resonant single phase AC link driven by a three phase bidirectional converter unit AC link is feeding for a single phase to six phase bidirectional converter. The proposed methodology is a general purpose electronic three phase to six phase conversion system, suitable for applications such as six phase induction motor. Also, it can be used as the front end power conversion stage for a six phase PMSG based wind energy harvesting system, and used for the fault tolerant STATCOM units. The proposed system can replace the conventional STAR/STAR and STAR/DELTA three phase transformer combination systems needed for 12 pulse rectifiers used in HVDC. The proposed system has been validated using simulations in the MATLAB SIMULINK environment and the relevant experimental verification.
