摘要
通过对传统的空间电压矢量调制方式的研究,提出了一种改进型的空间电压矢量调制方式,并给出了此改进型SVPWM调制方法下的各矢量作用时间的推导.相对传统的调制方式,此方法能够同时满足变频器输出在高频段和低频段的需要,适应了不同应用场合下的要求.实验结果证明本方法切实可行,具有一定的推广价值.
Through the study of conventional SVPWM modulation patterns, an improved SVPWM modulation pattern is proposed, with the deduction of the time every vector works. Compared to the conventional patterns, this modulation pattern satisfies the demand of inverters on the bands of both low-frequency and high-frequency better. The experiments validated its correctness.
