2、改变抽头型,将自耦变压器做成多个固定抽头,通过继电器或可控硅(固态继电器)做为开关器10件,自动改变抽头位置,从而实现输出电压的稳定。
该种型稳压器优点是电路简单,稳压范围宽(130V-280V),效率高(≥95%),价格低。而缺点是稳压精度低(±8~10%)工作寿命短,它适用于家庭给空调器供电。

1、伺服控制器通过自动化接口可很方便地进行操作模块和现场总线模块的转换,同时使用不同的现场总线模块实现不同的控制模式(RS232、RS485、光纤、InterBus、ProfiBus),而通用变频器的控制方式比较单一。
2、伺服控制器直接连接旋转变压器或编码器,构成速度、位移控制闭环。而通用变频器只能组成开环控制系统。
3伺服控制器的各项控制指标(如稳态精度和动态性能等)优于通用变频器。
