| 摘 要： | 为了改善有源滤波器的无功补偿特性，提出了一种控制电流逆变器型有源滤波器的新方法．电流逆变器是通过储能电感器电流的负反馈改变电压ｕｃ的相角进行控制的，这样能维持储能电感电流平均值基本不变．本控制方案是基于对电压ｕｃ波形的跟踪控制，它能在不引入阻尼电阻的情况下有效地防止由等效电感与滤波电容Ｃｃ引起的振荡。同时，该控制方法不需检测和计算负载有功功率及其它功率成份．模拟分析的结果验证了本文提出的控制方法．

| Abstract: | A new control method for active current-source-inverter filters is proposed in order t o improvereactive compensation characteristics. The current-source-inverter is controlled by varying the phasor of voltageuc, through feedback of the DC current in the energy-stored reactor, to keep the current nearly constant. Thecontrol method, based on following the tracks of voltage uc, can effectively suppress the transient oscillationscaused by the equivalent inductance and capacitance Cc without using any damping resistors. Meanwhile, thismethod need not sense and compute the reactive power component. The simulation results have verified theProposed control method. |
