摘　　要：针对一种降低逆变器容量的混合有源电力滤波器,详细介绍了其在三种控制方式下的工作原理、性能特点和等效电路,搭建了容量为10kV.A的混合有源电力滤波器实验样机,并进行了三种控制方式的实验和分析。实验结果表明,采用复合控制方式,该结构中逆变器容量仅为整个滤波器容量的4.42%,而该滤波器投入后,电网电流总谐波畸变率从26.95%下降到4.25%,补偿效果良好且优于其他两种控制方式。This paper presents three control methods for a hybrid active power filter （HAPF） , which is reduced the rating of its converter. Their principles, filtering performances and equivalent circuits of the HAPF are discussed in detail. Experiment waveforms are obtained in a laboratory prototype, rated at 10kVA. Experiment results prove the converter rating accounts for only 4.42% of the HAPF rating while the total harmonic distortion （THD） of the system current is reduced to 4.25% from 26.95% using the combined control method, which is better than the other control methods.
