摘要
有源电力滤波器是一种谐波补偿装置,由于LCL滤波器兼顾了低频段增益和高频衰减,所以可用LCL滤波器作为并联型有源电力滤波器的输出代替传统的单电感滤波器。对LCL滤波器进行了分析,并搭建仿真模型对其进行仿真,证明了带LCL滤波器的并联型有源电力滤波器能够有效地滤除开关纹波。
Active power filter is an important type of power electronic device which is used for harmonic compensation. The LCL- filter acting as the output filter of shunt active power filter could take the place of the L-filter for considering both gain of low frequency band and decay of high frequency band. The LCL-filter was analyzed and the simulation model was built. The simulation result shows that the shunt active power filter with the LCL-filter is sufficient for attenuating switching harmonic ripples.
