摘　　要：推导出三角形接法异步电机采用空间矢量脉宽调制(SVPWM)技术时,空间参考电压矢量的扇区判定方法及各扇区内基本空间电压矢量作用时间;给出了基于恒压频比的三角形接法异步电机SVPWM转速闭环控制系统框图及软件流程图,通过赛米控控制器实现了该控制算法;实验证明在SVPWM控制策略下,三角形接法异步电机运行良好,转速闭环精度高、稳定性好,与正弦脉宽调制(SPWM)控制策略相比更加节能。Sectors’ criterion of space reference voltage vector and operation times of each sector’s base space voltage vectors were deduced while Δ-Connection asynchronous motor was controlled using Space Vector Pulse Width Modulation(SVPWM) technology. Δ-Connection asynchronous motor’s speed close loop control system block and software flow chart based on constant V/F and SVPWM were presented, the control algorithm was realized through Semikron controller. The experiment proves that when using SVPWM control strategy, Δ-Connection asynchronous motor operates well with high speed close loop precision and good stability and SVPWM control strategy is more efficient in power saving than SPWM control strategy.
