一种用于三相PFC,APF和STATCOM的通用矢量控制器

A Universal Vector Controller for Three-phase PFC, APF, and STATCOM

功率因数校正器(PFC),有源滤波器(APF)和静止同步补偿器(STATCOM)是输配电系统中不可缺少的器件。理论和实验表明单周期控制策略控制三相PFC,APF和STATCOM,性能良好,电路结构简单,成本低。本文通过回顾PFC,APF和STATCOM单周期控制下的关键控制方程及电路,提出了一种通用控制电路,进一步研究表明该控制电路可以方便植入一种芯片控制所有的变换器。最后,通过实验和仿真结果证实了该理论的正确性。

Power Factor Corrected （PFC） rectifiers, Active Power Filters （APF）, STATCOM are indispensable components in power transmission and distribution systems. The theory and experiments have demonstrated that one-cycle control is capable of controlling three-phase PFC, APF, STATCOM, featuring excellent performance, simple circuitry, and low cost. In this paper, the control key equations and circuits for one-cycle controller controlled PFC, APF, STATCOM are reviewed, then based on the observation a universal control circuit has been developed, further study indicates that the new control circuit can be easily integrated into one chip to control all above converters. Finally the concept was verified by experimental and simulation results.
