摘　　要：提出了基于并联型三相三线制有源滤波器的优化设计的PI控制方法,该方法的优点是对检测到电流误差信号为控制对象,用滞环比较器构成区域判别器,在此基础上实行滞环电流控制。在同样的控制精度下,该方法可以有效得降低开关频率,减小有源滤波器开关损耗。计算机仿真结果验证了这一方法的有效性。An optimization design method of PI control is introduced, which is based on parallel form of APF. It is characterized that the control objectives are phase current errors, hysteresis comparators are used to consist of the detector, hysteresis current controlling is applied in this system. With the same control precision, this method can effectively lower the switching frequency, reduce the swithing loss and improve the performance of APF. It is validated by the computer simulation results.
