摘要 传统的共直流母线开绕组电机驱动系统的调制策略主要有三种:交替子六边形脉冲宽度调制(PWM)、中间六边形PWM和解耦SVPWM,但单一调制策略下无法兼顾电压输出范围和零序电压。该文提出一种移相解耦调制策略,该策略是在解耦SVPWM的基础上将两个逆变器的电压矢量夹角也作为一个控制量,通过调节该夹角可以使驱动系统既有较宽的输出电压范围,又能在全输出电压范围内具有较小的零序电压。最后,利用基于dSPACE DS1007的实验平台,分别通过实验验证了所提方法的正确性和有效性。

Abstract:There are three main modulation strategies for open-winding motor drive system with common dc bus: alternate sub-hexagonal center PWM (ASHC-PWM), middle hexagon PWM and decoupling SVPWM. The voltage output range and zero sequence voltage cannot be considered under a single modulation strategy. A phase-shift decoupled SVPWM control strategy is proposed in this paper. Based on decoupling SVPWM, the proposed strategy takes the phase angle between the two voltage vectors as a control variable. By shifting the phase angle, the OW-PMSM can achieve wide output voltage range and the smallest zero sequence voltage during the full output voltage. Finally, the correctness and validity of the proposed method are verified by simulations in Matlab/Simulink and experiments using the experimental platform based on dSPACE DS1007.
