摘　　要：提出了谐波电流检测方法,利用电压源非线性负载的平均直流输出电压和电流来代替典型负载电流和源电压。基于MATLAB/Simulink工具,设计了电容负载全桥二极管整流器单相交流系统的模型,并分析了产生正弦参考电流和滤波参考电流的逐级仿真结果,证明了该谐波检测方法成功地达到了产生单相APF参考电流信号的目的。The harmonic current detection method is proposed. The average DC output voltage and current of voltage source nonlinear load are used to replace the typical load current and source voltage. Based on the MATLAB/Simulink tool, the model of a single-phase AC system with a capacitive load full-bridge diode rectifier is designed. The step-by-step simulation results of generating sinusoidal reference current and filtering reference current are analyzed. It is proved that the harmonic detection method successfully achieves the purpose of generating single-phase APF reference current signal.
