摘　　要：有源电力滤波器(APF)是谐波抑制和无功补偿的有效方法。采用定频积分控制的有源电力滤波器摆脱了先检测谐波和无功电流,然后根据检测信号产生补偿电流的传统控制方法,简化了有源电力滤波器的结构。将该方法用于三相4线制有源电力滤波器,抑制谐波,提高功率因数并解决三相不平衡问题。The active power filter is an effective method to mitigate harmonic currents and compensate reactive power. Active power filter with unified constant-frequency integration control make it get rid of the traditional control method of sensing harmonic and reactive current and then generating compensating currents according to signals sensed. It simplifies the structure of active power filter. A three-phase four-wire active power filter with this control method was proposed to mitigate harmonics and improve the power factor and eliminate the imbalance between three phases.
