摘要

以一台逆变器驱动两台双Y移30°永磁同步电机(PMSM)的串联系统为例,给出了串联系统的工作原理,为了更好地实现两电机的解耦运行,提高直流母线利用率,改善逆变器电流输出波形,提出了一种新颖的最大四矢量( BFV-SVPWM)控制策略,具体分析了BFV-SVPWM的基本原理及具体实现方法.在MATLAB/Simulink环境下,对电机的变速运行进行了分析,与传统控制方法相比,验证了所提出的BFV-SVP-WM控制策略的可行性及优越性.%A two six-phase permanent magnet synchronous motor( PMSM) with dual-star windings series-connected system supplied by a single inverter was proposed. To achieve decoupling operate of this series system, a novel BFV-SVPWM strategy was presented which can increase DC bus utilization and improve inverter output current waveform . Basic principles and implementation method of the BFV-SVPWM were illustrated. The variable speed operat-ings of the sens-connected system were simulated under MATLAB/Simulink. Simulation results showed the feasibility and superiority of the BFV-SVPWM control strategy.
