摘要: 将空间矢量调制技术应用于有源电力滤波器的电流控制.用差分方程将APF的电流控制转换为对功率电路输出电压的控制,以有效地降低系统方程求解的复杂程度,并综合考虑电源电压及滤波电感等参数的影响,以提高系统控制的精度.仿真和实验结果表明,采用所提出的方法,当负载突变时,系统具有良好的动态响应特性.Abstract: Space vector modulation(SVM) was applied in current control of active power filters(APFs).Differential equations were used to transform current control of an APF to voltage control of the inverter to decrease the complexity in solving the system equations.The factors such as filter inductance and source voltage were taken into account to improve control precision.The results of simulation and experiment show that,with the proposed method,an APF has good dynamic characteristics when load or source voltage varies suddenly.
