摘要
针对 6等分空间电压矢量 PWM磁通转速不平衡和电流畸变的问题 ,在理论分析和仿真研究的基础上 ,提出了一种细分电压空间的改进算法。并提出了基于数字信号处理器的数字实现方法 ,该方法有效地改善了磁链幅值的波动及磁链旋转速度的不对称性 ,从而减小了电流畸变。
Aiming at the imbalance of stator flux′s velocity and current aberration of induction motor driven by six parts voltage space vector PWM inverter,a new method for subdivide vector space is presented in this paper based on both theory and experiences. There also make study on digital implement for this system. Simulation results indicate that this method amends the fluctuating and asymmetry of flux effectively,decrease current aberration consequently.
