摘要
Abstract
Aiming at the shortcoming that the traditional space vector pulse width modulation(SVPWM)algorithm has com-plex computation,a control strategy of three-level inverter SVPWM algorithm based on 60o coordinate is proposed in this paper. The control strategy can greatly simplify the reference vector sector determination and the switching vector action time calcula-tion of traditional SVPWM algorithm. The calculation workload of the controller was reduced by the research on the sectors size rule judgment,action time calculation and action sequence of basic vector in the g-h non-orthogonal coordinate system. The re-sults of Matlab/Simulink simulation verify the correctness and validity of the control strategy.关键词
