摘　　要：分析了多重化大功率有源电力滤波器的基本结构及控制系统的构成,采用一种基于负载基波电流作为参考电流的控制模式,提出了在该模式下多模块并联时的均流控制方法。应用该方法设计基于DSP和CPLD的数模混合控制系统,给出了采用该系统的二重化有源电力滤波器的实验结果,结果表明,能有效补偿非线性负载产生的谐波,具有很好的补偿效果。The configuration and operation principle of the active power filter （APF） with multiple PWM converters are introduced and analyzed. The control mode is adopted by load fundamental current as reference, and the current-sharing control method is pro- posed by this mode. According to the control purpose, the digital-analog hybrid control system based on DSP and CPLD is presen- ted. Finally, the experimental results of the APF adopting the proposed control system are given. It is shown that the compensation properties of the APF are very good.
