摘要在混合型有源电力滤波器中, 输出滤波器起着抑制逆变器开关纹波和保证系统稳定可靠运行的重要作用。针对这两种功能, 首先从抑制开关纹波作用中限定了输出滤波器的参数范围;然后通过建立整个系统的数学控制模型, 从保证系统控制稳定性的角度对输出滤波器参数进行设计。在此基础上, 为了获得一个经济、可靠, 适合高压大功率应用的混合型有源电力滤波器, 提出了一种新型输出滤波器阻尼控制策略, 解决了传统输出滤波器参数设计中阻尼电阻损耗过大的问题。实验结果表明, 该分析方法和控制策略能使混合型有源电力滤波器更加可靠、节能和适合大功率应用。

Abstract：The inverter switching ripple suppression and the reliability assurance of the output filter for the hybrid active power filter is analyzed in this paper. The range of the parameters of the output filter is confine to the function of the inverter switching ripple suppression. A control model of the hybrid active power filter is constructed to analyze the stability influence of the output filter and parameters design, taking into account the effect of the power system, the main circuit of the hybrid active power filter and its control circuit. A novel damping control strategy of the output filter is proposed, which solves the loss of the damping resistor and favorably applies in the high voltage and high power grids. Experimental results from a 10kW prototype prove that the proposed control strategy can improve the economy and reliability of the hybrid active power filter.

Key words： Hybrid active power filter output filter switching ripple damping control
