摘　　要：从三相交交变频器输出谐波电压入手,分析推导了交交变频同步电动机调速系统输出谐波转矩的解析计算公式.通过一个具体算例,计算得到了其主要次谐波的频谱.理论计算结果得到了仿真计算的验证,二者均正确地反映了转矩谐波的变化规律.Starting with the analysis on output harmonic voltage of 3-phase 6-pulse cycloconverter, the analytic calculating equation on harmonic torque of the speed regulating control system with cycloconverter-fed synchronous motor is obtained. The main harmonic spectrum of an actual example is achieved by this equation. The theoretic results are validated by simulation calculation. Both the theoretic results and simulation ones denote the characteristic of harmonic torque correctly. This analysis can be used as a certain reference for harmonic torque calculation of similar system and filter device design.
