摘要： 针对某些场合特定次谐波含量严重超标、无功不足的问题，提出了一种新型无变压器型并联混合有源电力滤波器拓扑结构.该拓扑由有源部分与无源部分组成，在无源部分实现无功补偿的基础上，利用有源部分补偿谐波.同时，系统利用无源部分串联分压和串联谐振，大大降低了有源部分工作电压，进而减小有源部分的容量.通过分析该新型拓扑电路的工作特点，建立系统的数学模型，采用解耦控制方法实现对系统的有效控制.实验结果验证了方案的可行性.

Abstract: A novel Parallel Hybrid Active Power Filter topology without transformer proposed is against the problem of excessive subharmonic content and insufficient reactive power in some cases, which consists of active and passive parts, and it increases active part to compensate harmonics on the basis of passive part to realize reactive power compensation. The system makes use of the working characteristics of the passive part series partial voltage and series resonance to reduce the active part working voltage low, and then reduce the capacity of the active part. After analyzing the working characteristics of the new topological circuit, a mathematical model of the system is established, using the decoupling control method to achieve effective control of the system. Experimental results confirm the feasibility and advantages of the proposed method.

Key words: hybrid active filter, transformerless, specific harmonic, topology
