摘　　要：针对许多滤波器设计时只注重谐波滤除,却忽略逆变器效率的问题,从调整无功功率的角度,提出一种LC滤波器的设计方法。该方法既满足了抑制谐波含量的要求,又提高了电源利用率。通过对不间断电源(UPS)阻性、感性、容性负载进行分析,验证了该方法的有效性。Aiming at the problem of ignoring inverter’s efifciency when harmonic smoothing is paid attention to in the design of many iflters, this paper proposed a kind of LC iflter design method from the corner of adjusting reactive power. This method not only met the re-quirement of suppressing harmonic content, but also raised power supply utilance. Resistive, inductive and capacitive loads of uninterruptible power source （UPS） were carried out analysis to verify the validity of the method.
