摘要
控制逆变器直流电容的平均电压与电压波动为适当值是保证并联型电力有源滤波器具有良好补偿性能的一个重要因素。本文对并联型电力有源滤波器直流电容平均电压与纹波电压的变化规律进行了研究,分析了直流电容平均电压与纹波电压对并联型电力有源滤波器性能的影响,在此基础上提出了相应的直流电容平均电压与纹波电压的一种控制方法,给出了使并联型电力有源滤波器性能达到最佳时直流电容平均电压应满足的条件。
Controlling the DC capacitor average voltage and fluctuant voltage at an adequate value is an important factor which guarantees the excellent compensation characteristics of shunt active filter (APF). This paper discusses the chang rule of DC capacitor average voltage and fluctuant voltage, analyses the influence of DC capacitor average voltage and fluctuant voltage on the performance of APF, then control method of DC capacitor average voltage and fluctuant voltage is presented . The condition which makes the performance of the APF best is proposed.
