摘　　要：有源电力滤波器主电路结构的研究已经比较成熟,其性能的提高主要依赖于所采用的控制方法。该文研究了单相有源电力滤波器、电源及非线性负载之间能量交换机理;在此基础上对变流器直流侧电容电压的稳定问题进行了理论分析,并提出了一种简单的应用于单相电压源型有源电力滤波器的数字化控制方法。该方法检测量少、算法简单、开关频率恒定、易于数字化实现,仿真结果验证了理论分析的正确性。For the maturated study of main circuit configuration, the development of APF mainly depends on its control method. Based on the research of energy commutation among APF, source and nonlinear load, this paper analyzes the stability of DC bus capacitor voltage theoretically and presents a novel simplified digital control method for voltage source single-phase active power filters. This method is few in the amount of sensors, simple in algorithm, fixed in switching frequency, and easy in digital control realization. Its validity is proved by simulation results.
