电压型变频器主电路包括：整流电路、中心直流电路、逆变电路三部分组，交-直-交型变频器结构见附图1 
2）中心滤波电路：整流后的电压为脉动电压，有必要加以滤波；滤波电容CF除滤波效果外，还在整流与逆变之间起去耦效果、搅扰、进步功率要素，因为该大电容贮存能量，在断电的短时间内电容两头存在高压电，因此要在电容充沛放电后才可进行操作。 
4）逆变电路： 逆变管V1~V6组成逆变桥将直流电逆变成频率、幅值都可调的沟通电，是变频器的中心部分。常用逆变模块有：GTR、BJT、GTO、IGBT、IGCT等，一般都选用模块化结构有2单元、4单元、6单元
（1）电机绕组为理性具有无功重量，VD1~VD7为无功电流返回到直流电源供给通道 
（3）V1~V6进行逆变进程是同一桥臂两个逆变管不停地交替导通和截止，在换相进程中也需求D1~D6供给通路。 
因为逆变管V1~V6每次由导通切换到截止状况的瞬间，C极和E极间的电压将由近乎0V上升到直流电压值UD，这过高的电压增长率可能会损坏逆变管，吸收电容的效果就是下降V1~V6关断时的电压增长率。 
电机在减速时转子的转速将可能超越此时的同步转速（n=60f/P）而处于再生制动（发电）状况，拖动体系的动能将反应到直流电路中使直流母线（滤波电容两头）电压UD不断上升（即所说的泵升电压），这样变频器将会发生过压维护，甚至可能损坏变频器，因此需将反应能量耗费掉，制动电阻就是用来耗费这部分能量的。制动单元由开关管与驱动电路构成，其功能是用来操控流经RB的放电电流IB。
