摘　　要：首先分析了比例谐振控制器的原理,改进了其对电网频率畸变敏感的特性,然后建立了基于准比例谐振控制器的有源电力滤波系统。利用DSP28335实现了该系统的集成控制,通过实验进行了验证,并与传统PI调节器进行了对比。该有源电力滤波器有效地降低了电网电流的畸变率(THD),提高了电能质量,并具有较高的稳定性。First, the principle of an ileal lbroigortional resonant controller is analyzed, and then a improvement over the sensitivity to the frequency of grid voltage is proposed. An active power filter system is developed by Using the sub-proportiorial resonant con-troIler. The overall control of the system is carried out bsed on DSP28335. Experiments are provided to show the effectiveness and the advantage over a traditional PI controller. The trilter can remove the harmonic qurrents and the perf6rmance is with high stability. .
