摘要
单周控制(one cycle control,OCC)因其控制结构简单,控制精度高,响应速度快等优点,已被广泛用于有源电力滤波器(active power filter,APF)的控制。目前单周控制技术主要集中在并联型APF的控制中,而对单周控制应用于串联型APF仍需要进一步研究。文中将单周控制理论应于直流侧串联型APF,通过对其主电路工作原理的分析,导出了用于DC(direct current)侧串联型APF的单周控制数学关系,并建立了控制方程。仿真结果验证该理论的正确性与可靠性。
One cycle control has been widely used for active power filters (APF) because it has a simple structure, high precision, and fast response. One cycle control techniques mainly concentrate on parallel APF at present, but its application in series APF needs to be explored further. We introduced the one cycle control method to a direct current (DC) side series APF. By analyzing its working principle, mathematical models based on one cycle control theory were derived for the DC side series APF, and the control equations were established. Simulation results verify the correctness and reliability of the method proposed.
