摘　　要：给出了一种新型混合有源滤波器的拓扑结构,该滤波器由有源滤波和无源滤波两部分组成。利用电路结构的特点,在实现对电网进行无功补偿和抑制特定次谐波的基础上,大大降低了有源滤波部分的容量。在对该滤波器拓扑结构分析的基础上,建立了系统数学模型,给出系统的具体控制策略,完成了控制系统的设计。最后通过仿真分析验证了这种混合型电力滤波器拓扑结构及其控制策略的有效性。A new hybrid power filter is presented inthis paper.It is composed of active power filter （APF）and passive power filter（PPF）.The reactive power compensation for the grid and harmonic suppression can be achieved by this filter.Meanwhile, the capacity of active power fiheris decreased greatly by it.Based on the analysis of the topology of the filter, the mathematical model of the system is established and the control strategy of the system is given.Finally, the simulation results verify the effectiveness of the hybrid power filter＇ s topology and control strategy.
