摘　　要：随着电力电子技术广泛的应用在生产和生活中,致使电力系统谐波污染问题日益严重。无源滤波器虽然成本低,但是不能较好的治理谐波,有源滤波器虽然滤波效果较佳,但是成本过高,不利于推广,将有源滤波器和无源滤波器并联而成的混合型有源滤波器可克服单独使用无源和有源滤波器的缺点。基于此,分析了并联混合型有源滤波器的拓扑结构、等效电路与控制方式,最后通过实验验证了并联混合型有源滤波器的优越性。Along with the power electronic technology is widely used in the production and life, harmonic pollution prob- lem of the electric power system is getting worse. A passive filter is low cost, but not good governance harmonic, active filter filtering effect is better, but the cost is too high, go against the promotion, will be active filter and passive filter and a parallel hybrid active filter can overcome used alone without source and active filter faults. Based on this, this pa- per analyzes the parallel hybrid active filter topology, equivalent circuit and control method, the experimental results Verify the parallel hybrid active filter superiority.
