摘 要: 有源滤波器控制策略的优劣直接决定其滤除谐波的性能,采用空间矢量脉宽调制技术实现对谐波的调制,并进行仿真验证.仿真结果表明,该算法产生的脉宽指令作为逆变器中各开关器件的通断控制信号,控制的结果能保证补偿电流实时跟踪其指令电流的变化,精确度与准确度均可满足系统要求. The control strategy of active power filter will determine the performance of harmonic filter directly.Using space vector pulse width modulation technology to modulate the harmonics,and conduct simulation.Simulation results show that the algorithm produces the pulse width of each instruction as the inverter switching device off control signal,and the control results can ensure the compensation current will tracking to the order current changes real-time,precision and accuracy can meet the system requirements.
