| 摘 要： | 建立了采用三桥臂变流器为主电路的三相三线制有源电力滤波器的非线性数学模型.针对目前电力电子变换器装置中动态性能差的特点,对有源电力滤波器的电流内环提出一种滑模变结构控制算法,电压外环采用传统的PI控制.试验结果表明,该方法动态响应快、鲁棒性强,具有更好的谐波抑制性能.

| Abstract: | The nonlinear mathematical model of active power filter(APF) for three-phase three-wire system was built by use of three-legged converter as main circuit.Aiming at the poor dynamic performance of power electronics converter device,a sliding-mode control algorithm frame for the current-loop was proposed,and the traditional PI control for the out-voltage-loop was proposed.The experimental results show that this method has a quick dynamic response,strong robustness and better harmonic control performance. |
