| Abstract: | A method of SVPWM over-modulation which is easy to be implemented was proposed. According to the continuity of angle and amplitude, the over-modulation range could be divided into two parts. The theory of over-modulation and the expression of the fundamental voltage magnetic in each part were presented with each part's characteristic. At last, based on the theory of over-modulation, a realizable engineering method was proposed. This method was used to finish the experiment and the theory was proved to be available. |
