摘要
为了改善有源滤波器的非有功补偿特性．本文提出了一种控制电压逆变器式有源滤波器的新方法。电压逆变器是通过储能电容器电压和滤波器输入电流及其导教的负反馈进行控制的．它们分别起着维持储能电容器电压和防止由供电系统等效电感与滤波电容Cf引起的振荡的作用，在电路中不需引入阻尼电阻。该控制方法的优点在于，不需要检测和计算非有功功率成份而能保持电源功率因数近似为1。模拟分析的结果证明了本文提出的控制方法的可靠性。
A novel control method for activc voltage source inverter filters is proposed in order to obtain good nonactive compensation charaeteristies. Thc voltage source inverter is controlled with feedback loops of DC voltage on energy-storing capacitor to support near-constant voltage on him.and of filter input current and his derivative to suppress the transient oscillations caused by equivatent inductance of power system and capacitance Cf without inserting damping resistors. The principal advantage of this control scheme is that it can maintain a near-unity source power factor without sensing and computation of the associated nonactive power component. The simulation results demonstrate the validity of the proposed control method.
