摘要
在论述二极管钳位型三电平逆变器的拓扑结构的基础上,介绍了空间电压矢量(SVP-WM)的基本原理、SVPWM算法的区域判断和矢量作用时间计算,讲解了一种判断小扇区的新型方法。通过MATLAB进行系统仿真,得出仿真结果,证明了三电平逆变器的优点。
This article discusses the tapological type structure of diode clamp type three-level inverter, introduces the basic principle of space voltage vector （the basic principle of implementing SVPWM）, the regional judgment and implementing SVPWM algorithm of vector action time calculation and explains a new method of judging small sector. Finally, through MATLAB simulation model. It obtains the simulation result which shows the advantages of three-level inverter.
