Abstract :
This paper presents an ac-dc-ac reversible six-phase machine drive system. It is composed of single-phase bridge converters connected in series in the grid side and single-phase bridge converters connected at the machine phase terminals. The proposed topology eliminates the input isolation transformers and reduces the power processed by converter switches and the harmonic distortion in the grid side. The model and the control strategy have been developed. Simulation and experimental results are presented.
