Abstract:This paper, based on the three dimension (3D) coordinates, presents the cause of the zero-sequence voltage in the open winding asynchronous motor system which is driven by double inverters with single power supply. The large vectors which have zero-sequence voltage are selected to realize PWM. For eliminating the zero-sequence voltage, the space zero vectors are inserted in every control period. This modulation algorithm is easy to be realized by digital controller. The validity of the proposed method has been verified by MATLAB simulation.
