【摘要】 由交交变频器输出作为交流励磁的发电系统中，输出电力谐波可分为两类：“负载谐波”与“电源谐波”。本文分析了这两类谐波的特性，讨论了电源谐波的检测方法，提出了优化的混合式滤波器结构，对设计中的特殊问题作了详细分析，最后给出了实验结果作为本研究的验证。更多还原

【Abstract】 The power harmonics generated by the cycloconverter in an a.c.excited generation system can be grouped into two sorts:“Load Harmonics” and “Source Harmonics”.In this paper,the natures of these two kinds of different harmonics was analyzed and the detecting methods of voltage datum for the source harmonics were discussed.The optimized topologic structure of hybrid filter was proposed,and finally,the experimental results were given to verify the study.更多还原
