140XBP01600 现场总线
低压通用变频输出电压为380～650V，输出功率为0.75～400kW，工作频率为0～400Hz，它的主电路都采用交-直-交电路。其控制方式经历了以下四代。
1.U/f=C的正弦脉宽调制(SPWM)控制方式
其特点是控制电路结构简单、成本较低，机械特性硬度也较好，能够满足一般传动的平滑调速要求，已在产业的各个领域得到广泛应用。但是，这种控制方式在低频时，由于输出电压较低，转矩受定子电阻压降的影响比较，使输出大转矩减小。另外，其机械特性终究没有直流电动机硬，动态转矩能力和静态调速性能都还不尽如人意，且系统性能不高、控制曲线会随负载的变化而变化，转矩响应慢、电机转矩利用率不高，低速时因定子电阻和逆变器死区效应的存在而性能下降，稳定性变差等。因此人们又研究出矢量控制变频调速。
2.电压空间矢量(SVPWM)控制方式
它是以三相波形整体生成效果为前提，以逼近电机气隙的理想圆形旋转磁场轨迹为目的，一次生成三相调制波形，以内切多边形逼近圆的方式进行控制的。经实践使用后又有所改进，即引入频率补偿，能速度控制的误差；通过反馈估算磁链幅值，低速时定子电阻的影响；将输出电压、电流闭环，以动态的精度和稳定度。但控制电路环节较多，且没有引入转矩的调节，所以系统性能没有得到根本改善。
