6SN1123-1AB00-0CA1是西门子的一个伺服驱动器型号1。它的主电路主要由整流电路、滤波电路、逆变电路及制动单元等几部分构成1。

整流电路由VD1~VD6组成三相桥式全波整流电路将三相交流电整流成直流电1。滤波电路则是整流电路输出的直流电压为脉动的直流电压，因而需滤波电路滤去电压波纹，同时它还在整流电路与逆变电路起到储能作用1。

逆变电路由开关管V1~V6构成逆变电路将直流电压逆变成三相频率、电压可调的交流电以驱动三相电动机，是变频器实现变频的关键环节1。

限流电路由限流电阻R及开关K构成，由于上电瞬间滤波电容端电压为零，上电瞬间电容充电电流较大，过大的电流可能损坏整流电路，为保护整流电路在变频器上电瞬间限流电阻串联到直流回路中，当电容充电到一定时间后通过开关K将电阻短路1。

制动电路由制动电阻RB及开关管VB构成，主要作用是用于消耗电动机反馈回来的能量，避免过高的泵升电压损坏变频器1。
