有源电力滤波器可以在实际系统中使用，具有成本效益，插入一些并联或串联配置的无源元件。所得到的混合滤波器可以被设计为通过无源元件提供主导的低次谐波消除和无功功率支持，从而减少有源滤波器对应部分上的负担。在本文中，率减少并联有源滤波器时，它是并联适当的无源调谐谐波滤波器估计。有源滤波系统基于适当的控制方案。并联型有源滤波器的仿真和实验结果，沿着额定值降低的估计值，表明混合并联型滤波系统在补偿谐波和无功功率方面是相当有效的，并且具有成本效益。
Active power filters can be cost-effective for use in practical systems with the insertion of a few passive elements in shunt or series configuration. The resulting hybrid filters can be designed to provide dominant lower order harmonic elimination and reactive power support by the passive elements so that the burden on the active filter counterpart is reduced. In this paper, the rate reduction in the shunt active filter is estimated when it is connected in parallel with suitable passive tuned harmonic filters. The active filtering system is based on an appropriate control scheme. The simulation and the experimental results of the shunt active filter, along with the estimated value of reduction in rating, show that the hybrid shunt filtering system is quite effective in compensating for the harmonics and reactive power, in addition to being cost-effective.
