摘　　要：对级联型H桥变换器的阶梯波特定消谐技术进行了研究,运用运筹学、数学建模以及SHEPWM和阶梯波调制方法来分析讨论阶梯波特定消谐技术中的总电压谐波畸变率(THD),通过选取固定的级联模块数以及特定的谐波求解THD,并且THD的解符合实际结果要求。The problem of step wave harmonic elimination technology of cascaded H-bridge converter is studied.The total voltage harmonic distortion rate(THD)of step wave harmonic elimination technology is analyzed and discussed by using operations research,mathematical modeling,SHEPWM and step wave modulation methods.Thd is solved by selecting fixed number of cascaded modules and specific harmonics,and the solution of thd meets the requirements of actual results.
