摘　　要：根据变流器直流侧滤波元件,将谐波源分成电流型和电压型谐波源。通过分析串联、并联APF对不同类型谐波源的补偿特性,确定了它们各自适合的补偿对象,串联或并联型APF分别适合补偿电压型或电流型谐波源。通过分析混合型APF的工作原理,推导出了其传递函数和谐波电流、电压的计算公式,实验结果验证了结论的正确性。The harmonic source can be classified into current harmonic source and voltage harmonic source on the basis of a transformer with a filter component on its DC side. Through analyzing the compensation characteristics of the shunt and the series active power filters to different types of harmonic sources, the suitable compensation objects are determined, the shunt or series APF should be used for compensating the current or the voltage harmonic source. And through analyzing the operation principles of the hybrid APF, its transmit function and the harmonic current or voltage's calculate formula is deduced. The experiment results show that the conclusion is correct.
