摘　　要：针对有源电力滤波器(APF)设计过程中对输出电感值的选取及制作存在的盲目性,提出基于瞬时值比较电流跟踪方式和三角波比较电流跟踪方式的电感值选取原则,并详细阐述基于定时器控制的瞬时值比较电流跟踪方式计算电感值的方法。根据有源滤波的特点提出了采用铁硅铝作为铁心材料,利用最小体积法对电感进行了优化设计。最后通过实验验证了电感选取和设计的合理性。Aiming at the blindness problem of output inductance selection during the design process of active power filter （APF）,the selecting principle with instantaneoas compared current tracking and triangle compared current tracking modes is proposed.The calculation method of instantaneous value comparison way which is controlled by timer is presented in detail.According to the characteristics of active filter,Fe-Si-Al is used and minimum volume method is adopted to optimize the design of inductance.Finally,the experimental rcsuhs verified the effectiveness of the proposed method.
