摘　　要：针对有源电力滤波器(APF)成本高的缺点,提出了将无源滤波器和APF串联起来的混合型有源电力滤波器(HAPF)。新型拓扑结构既弥补了无源滤波装置的固有缺陷,又能充分发挥APF的优势,降低了成本。研究了HAPF的滤波原理,分析了HAPF直流侧电压参数的确定方法。确定无源滤波器的调谐次数为7次,并单独对5次谐波进行补偿。最后验证了所提策略的有效性。Active power filter（APF） for high-cost disadvantage,hybrid active power filter（HAPF） which combine passive with APF is studied.Compared to conventional active filter,the new topology can make up for the inherent defects of passive filtering device while it can give full play to the advantages of APF,and greatly reduces the cost.The filtering principle of HAPF is studied,and the method of determining the parameters of the DC voltage for HAPF is analyzed.Determines the passive filter tuned to seven times and compensates 5th harmonic separately.Finally,the effectiveness of the new method is verified.
