摘要 本文研究了三电平逆变器的原理、及其空间电压矢量(SVPWM)调制方案、并利用SVPWM策略决定电压向量的开关顺序和相应的输出电压的方法。提出基于SVPWM的三电平逆变器转差频率控制的异步电动机的矢量控制系统,并进行了仿真,仿真结果显示,所设计的感应电动机转差频率控制系统具有较好的实用价值。 In this paper,a three-level neutral-point-clamped（NPC） inverter is studied comprehensively,and space vector pulse width modulation（SVPWM） method is studied too.Then,slip frequency control and speed sensor-less methods of induction motor,which is driven by a three-level NPC inverter,are studied and explored,further,also,a three-level inverter prototype system is built a lot of experimental results are obtained based on this prototype.
