| 摘 要： | 通过对传统SVPWM调制算法进行理论分析和算法推导,提出了一种新的差值SVPWM调制方法。该方法在每个控制周期内,直接采用三相电压差值来计算基本电压矢量作用时间,并由相电压之间从大到小排序来判定扇区,省去了传统实现方法中复杂的坐标矩阵变换、三角函数计算等矢量分解过程,简化了SVPWM算法步骤。进一步的仿真与实验,证明了该差值SVPWM算法正确、计算效率高、实时性强,节省CPU资源。

| Abstract: | A novel difference value space vector pulse-width modulation (SVPWM) algorithm is proposed in the paper based on the conventional SVPWM analysis. In the proposed method,the SVPWM is implemented through the 3 phase voltage difference computation,and judged voltage vector space's sector through the sequence of phase voltages,without coordinate transformations,trigonometric function,inverse trigonometric and vector decomposition to the sector in the conventional SVPWM method. The validity of proposed method is... |
