基于MSP430单片机的开关电源模块并联供电系统

摘要

In this paper, low-power MSP430 microcontrollers produced by two parallel power supply system,the use of integrated chip LM2596 converter output voltage 8V, power of 16W, the conversion efficiency of 65%,and maximum current up to 4.5A;two DC/DC module the current ratio can be automatically adjusted within 2%error.After testing, the basic part and the part played some of the indicators are in line with requirements.%本文采用低功耗单片机MSP430制作的两路并联供电系统，运用集成芯片LM2596转换输出电压8v，功率为16W，转换效率在65％以上，最大电流可达4．5A；两DC／DC模块的电流比可以自动调节，误差在2％内。经测试，基本部分和部分发挥部分的各项指标均符合要求。
