摘    要:提出了一种新型混合有源滤波器的拓扑结构.其基本思想是根据分流原理,对有源部分进行适当控制来等效增大系统支路的谐波阻抗,提高无源滤波器的滤波效果;将有源部分与基波谐振电路并联来减小有源部分容量,同时将基波谐振电路作为一组单调谐无源滤波器的部分和其他无源滤波器组一起构成分流支路;无源部分还可以提供很大无功补偿容量,而且不影响有源部分的容量.仿真和实验结果证明了所提出的混合有源滤波器的可行性和正确性.

关 键 词:混合有源滤波器  拓扑结构  基波串联谐振  无功补偿

Abstract:This paper proposes a new type hybrid active power filter. The basic idea is that the valid control of active filter is equivalent to increase the system harmonic impedance to enhance the performance of passive filters. One advantage of this is to reduce the power of the active filter by installing active filter in parallel of fundamental series resonance circuits. Besides, the fundamental series resonance circuits as parts of a set of passive filters with other passive filters construct the shunt circuits. Another advantage is that passive filters can supply high reactive power and this do not enlarge the capacitance of active filter. Simulations and experiment results have verified the effectiveness of the proposed topology.
Keywords:Hybrid active power filter  topology  fundamental series resonance  reactive power compensation
