Mathematical Model and Characteristics of Injection Type Hybrid Active Power Filter

在分析注入式混合有源电力滤波器(injection typehybrid active power filter,IHAPF)工作原理的基础上,从控制的角度提出电压型逆变器的数学模型,在此基础上建立IHAPF的数学模型,对其稳定性和谐波抑制能力进行分析,着重探讨控制器参数对IHAPF稳定性和谐波抑制能力的影响,并提出控制器参数选择方法。仿真和实验结果证明了分析的正确性。

The mathematical model of voltage source inverter was proposed based on the analysis of operating principle of injection type hybrid active power filter （IHAPF）. Then the mathematical model of IHAPF was presented. And the stability and harmonic suppression ability of IHAPF were analyzed. Specifically, the influences of the controller parameters to the stability and harmonic suppression ability were amply discussed. Furthermore, the design method of controller parameters was proposed. Simulation and experimental results verify the validity of the analysis in this paper.
