摘要
研究了一种单片机控制的单相方波输出后备式UPS,该系统实现了在市电不同状态下,系统逆变输出与市电的同相切换,实现了对设备的不间断供电;实现了对蓄电池的智能管理;可以与PC机进行通讯,便于用户监控等功能。分析了该系统的工作原理,给出了电路的硬件实现及软件算法框图,并给出了实验结果。
Square-wave passive standby UPS based on MCU is presented. There are some functions of the system： realizing the uninterruptible power supply according to following the track of grid and changing grid and inverter in phase when grid is abnormal; advanced battery management; communication and supervision with PC. The principle of the system is analyzed. The design of hardware and compiling of the software are given. Experimental results are presented to verify the analysis.
