| 摘 要： | 三相四桥臂拓扑结构的有源电力滤波器（APF）不但能抑制谐波电流,也能补偿三相不平衡。在此介绍了系统的拓扑结构;通过对四桥臂电压型变换器进行建模分析,得到了APF的控制策略;详细分析了APF的三维空间矢量脉宽调制法（3D-SVM）;最后搭建了一台实验样机。实验结果验证了控制策略和调制方法的正确性和有效性。

| Abstract: | APF with three-phase four-leg topological structure can suppress harmonic currents and compensate three-phase unbalance.The topological structure of the system isintroduced.The control strategy of APF was obtained based on the modeling analysis of the four-leg voltage-source converter.The three-dimensional space vector modulation(3D-SVM) for APF is also analyzed in detail.An experimental prototype was built.The experimental results validate that the control strategy and 3D-SVM is correct and effective. |
