在变频控制中，目前常用的是三相逆变桥，就像下面的图中一样。三相逆变桥中的U1,U2,V1,V2,W1,W2是控制6个IGBT的驱动信号；而三相逆变桥U,V,W分别接电机的三相绕组的引出端；三相逆变桥的工作原理这里简单介绍一下，逆变桥的上端接的是直流电压的正端，下端接的是直流电压的负端，这里该直流电压为VDC。三相桥由三个桥臂组成，如上图中U1,U2控制的IGBT组成一个桥臂；V1,V2控制的IGBT组成第二个桥臂；W1,VW2控制的IGBT组成第三个桥臂；所以当U1是高电平，且U2是低电平时，上臂的IGBT开通，下臂的IGBT关断，这样的话电机的U相对逆变桥的负端电压就约为该逆变桥的直流电压值，即为VDC。

增量编码器又称为脉冲盘式编码器，增量式编码器是将位移转换成周期性的电信号，再把这个电信号转变成计数脉冲，用脉冲的个数表示位移的大小。增量编码器结构与工作原理增量式编码器通过判断B相位差，是超前还是落后90度，可以判断编码器的旋转方向。增量式编码器输出的脉冲信号一般连接计数器、pl计算机,连接方式有3种如下：单相连接，用于单方向计数，单方向计数的时候。B两相连接，用于正反计数、判断正反方向和测试速度；Z连接用于带参考位置测量。
