摘　　要：研究交－ 交变频器供电励磁的发电、电动系统的谐波问题， 给出多种结构和工作模式交－ 交变频器输出谐波的解析表达； 根据交流励磁电机谐波正序、负序电路模型， 导出交流励磁电机空载及并网运行时电网谐波和电机谐波转矩的分析方法。通过计算实例分析和比较了几种系统的谐波特性。The harmonic issue in the AC excited machines (ACEM)fed by the cycloconverter was studied.Based on the firstly presented analytical expressions of outputs generated by the various type cycloconverters operated in different modes and the positive,negative sequence harmonic equivalent circuits of ACEM,the analysis method of harmonic voltage,current as well as torque in the no load or networked ACEM was derived.The harmonic nature of various schemes were also analyzed and compared.
