变频驱动主要使用的驱动波形主要有SPWM和SVPWM两种。SPWM原理简单、实现容易,是现在使用最广的一种变频驱动波形。但其有一个致命的弱点是其电源利用率不高（只有86％）、谐波成分大。因此,在新近开发的产品中其应用逐渐被性能优异的SVPWM所取代。SVPWM是一种电压利用率、低谐波成分的变频驱动波形,还有开关次数少、功率管功耗小等特点。同时,SVPWM还能很好的结合矢量控制算法、以最大限度的发挥设备的性能。因此被越来越多的变频设备所采用。-The main use of variable f

随着异步电机开始在交流调速领域占统治地位，针对高性能异步电机的调速系统
研究得到广泛关注。特别是 20 世纪 80 年代直接转矩控制（DTC）的出现，以其简洁高
效的控制方式，进一步提高异步电机的性能。但传统 DTC 存在转矩和磁链滞环宽度使
得稳态时也会产生转矩脉动。因此高性能控制需要窄的滞环宽度,相应要求高逆变器开
关频率。大功率场合下必须低开关损耗和良好转矩控制性能，传统 DTC 难以同时满足
需求。
