摘　　要：为提高有源滤波器的滤波性能,减少日趋严重的谐波问题,提出了一种滤波系统结构。详细分析了工作原理,用数学建模的方法,建立了该滤波系统的控制模型方程,分析了采用PWM控制下逆变器输出到电网过程中谐波电流相位的变化。该混合有源滤波器具有较大容量的无功补偿能力和较小的逆变器容量。实验和仿真结果证明了该混合有源滤波器的正确性和可行性,对滤波器的设计和使用具有重要的实用价值和理论指导意义。In order to enhance the performance of the hybrid active power filter, and to reduce serious harmonics problems day by day, a new type hybrid active power filter is proposed. This paper analyzes work principle and establishs the control model equation by mathematical modelling ,then analyzes the harmonic current phase＇s change in the inversion process under the control of pulse width modulation （PWM）. This hybrid active filter has larger reactive power compensation and smaller inverter capability. Experiment and simulation results have proved the validiby and feasibility of the proposed topology, which provides important practical and theoretical value to design and use of active power filter.
