基于单片机的后备式UPS的实现

Design of Passive Standby UPS Controlled by MCU

研究了用单片机控制的单相后备式方波输出UPS的控制技术及实现,分析了系统的工作原理,给出了硬件实现电路和算法框图,并测出了市电逆变相互转换等主要实验结果。

This paper introduces a controlling scheme for the single-phase off-line UPS by using MCU, and the principles of operation. The scheme of hardware, and software are presented.
