中文摘要：

针对整流桥谐波源负载．笔者通过对其电压型谐波源和电流型谐波源的谐波特性分析．指出DC侧并联型APF补偿电压型谐波源的不足，进而研究其对偶拓扑结构——DC侧串联型APF。对两种DC侧APF进行了单周控制理论实现和补偿特性效果比较。结果表明：DC侧并联型APF适合补偿电流型谐波源，DC侧串联型APF更适合补偿电压型谐波源．从而验证了理论分析与单周控制实现的正确性。

英文摘要：

For the harmonic source loads of rectifier bridges, DC side shunt active power filter （APF） is found inadequate for voltage type harmonic sources, therefore its dual topology-DC side series A,PF is studied by analyzing harmonic characteristics of the voltage type and current type harmonic sources. The results show that： DC side shunt APF is suitable for compensating current type harmonic sources, while DC side series APF is more suitable for compensatiing voltage type harmonic sources, which thereby verifies the correctness of theoretical analysis and the implementation of cycle control.
