摘　　要：使用STC12C5A60S2高速单片机为控制器,控制由TPS54340和LM3478芯片组成的降压和升压模块组,实现了一种高效率双向DC-DC变换供电系统。系统实现了UPS电源的功能,采用PID算法实现对电池的恒流充电,充电效率高达91%以上,采用恒压模式对电池进行放电(对负载恒压供电),效率高达93%以上。系统同时设计了过充保护功能以及自动切换充放电功能,可实现对输入电压、输出电压和电流的自动监测,可以直接挂接于无人值守的小型太阳能和风能智能监控、照明、信号灯控制等清洁能源应用系统。In this paper MCU,as control kernel,is used for controlling buck and boost module groups,which are consisted of TPS54340 and LM3478chips respectively,which are used to achieve a high efficiency bidirectional DC-DC converter power supply systems.The system realizes the function of UPS power.PID algorithm is presented for realizing the constant-current charging of the battery system.And charging efficiency is over 91%.The constant-voltage mode for the battery is discharged(for power supply to the load of constant voltage),and the efficiency is over 93%.Meanwhile,the system has the function of overcharge protection,which can monitor the input voltage,output voltage and the current automatically.The system can be applied for clean energy application system such as unattended small solar,wind power intelligent monitoring,and lighting,signal lamp control,etc.
