| 摘 要： | 有源电力滤波器(APF)被认为将代替传统LC无源滤波器,用来治理线路上非线性负载及开关器件产生的谐波和无功电流.APF为消除谐波,逆变器必须根据指令输出补偿电流,而谐波电流随时间快速振荡变化,因此电流控制器对谐波电流的跟踪能力决定了APF的性能高低.在此分析了并联型APF的电流控制数学模型,针对并联型APF提出一种简单...

| Abstract: | Active power filter(APF) is recognized as a substitute for classical passive LC filter in eliminating the pow-er line harmonics and reactive current due to nonlinear loads and switching devices.For eliminating harmonic cur-rents with APF,the inverter must be commanded to output compensating currents which are time varing with rapid vi-brations.Therefore,the tracking capability of the currents controller of the inverter dominates the performance of the APF.This article analyzes the current control model of t... |
