两组整流桥并联组成的大电流馈电系统在工业生产中有着广泛的应用。但整流桥并联馈电系统中存在着由于平衡电抗器和共用负载带来的电流反馈的耦合现象 ,对系统性能产生了许多不利的影响。该文在实践的基础上提出一种改进算法 ,可以有效地消除原算法中存在的电流耦合问题。新算法在没有改动硬件的条件下 ,仅通过简单的修改调节器软件的算法 ,就可以使系统在鲁棒性和快速性两方面都有较大的提高。该算法已应用于以 Intel80 C196 KC单片机为核心的十二相整流电路控制器 ,并取得了满意的结果。
Two sets of rectifier bridge in parallel form a large current feed system in industrial production has a wide range of applications. However, the coupling phenomenon of the current feedback in the rectifier bridge parallel feeding system due to the balance reactor and the common load has a lot of unfavorable influences on the system performance. This paper puts forward an improved algorithm based on practice, which can effectively eliminate the current coupling problem existing in the original algorithm. The new algorithm can improve the robustness and fastness of the system only by simply modifying the algorithm of the regulator software without changing the hardware. The algorithm has been applied to twelve-phase rectifier circuit controller with Intel80 C196 KC microcontroller as its core, and achieved satisfactory results.
