摘要
现代飞机上安装了大量的微处理机、计算机。由于电源之间正常转换而出现的电源短暂中断现象会对微处理机、计算机的工作产生干扰。研制不中断供电的电源系统已是刻不容缓的任务。本文讨论了电源正常转换时电源中断现象及原因。以现代大型飞机上的电源系统不中断供电技术为例,阐述消除电源中断的技术方案以及汇流条保护控制组件(BPCU),发电机控制组件(GCU)内有关不中断电源转换的逻辑。
A large number of microprocessors and computers are insta- lled on modern aircraft.Power interruption during normal bus transfer affects the operation of the microprocessors and the computers.It is most urgent that an AC power system that eliminates power interruption be de- veloped.This paper discusses the causes and effects of power interruption during normal bus transfer.Taking the no-break power supply technique on modern giant airplanes as an examle,it sets forth a scheme to elimi- nate power interruption,and a transfer logic for no-break power supply in the bus power control unit and the generator control unit.
