针对有源电力滤波器两种主要的控制方式偏差带控制和ＰＷＭ控制进行了仿真研究。对于（定）偏差带方式下偏差的选取给出了经验公式，讨论了偏差与平均开关频率之间的关系，并对这两种主要控制方式的补偿效果和优缺点进行了分析比较。仿真结果表明，偏差带控制方式更适合于有源滤波器的应用。这一结论对实际装置的研制有一定参考价值。
The two main control methods of active power filter are given, and the control of deviation band and PWM control are studied. The empirical formula is given for the selection of the deviation in the mode of deviation, and the relationship between the deviation and the average switching frequency is discussed. The compensation effects and advantages and disadvantages of these two main control modes are also analyzed and compared. Simulation results show that the deviation band control method is more suitable for the active filter application. This conclusion has certain reference value for the actual device development.
