摘 要: 针对嵌入式系统中存在多种不同供电电压的特点,利用AVR Butterfly提供的丰富的硬件接口资源控制一个有反馈的稳压电源,用C语言调用GCC设计软件程序,设计一种能够适用于多种不同嵌入式系统的智能电源,能够提供多种不同的输出电压,并且能够模拟多种不同电源供电情况,方便测试目标系统的稳定性和可靠性。在实际测试中,该电源能够模拟电源掉电等嵌入式系统常遇到的电源故障,并能对不同的系统预置不同的输出电压。 Because of there are many kinds of voltage in embedded system,a regulated feedback power supply is controlled by the plenty of interface of AVR Butterfly, and the software for AVR Butterfly is designed by C language call GCC, an intelligent power supply for many kinds of embedded system is designed and it can output variety of voltage, simulate different kinds of power supply state,so it can give convenience for stability and reliability test. It can simulate many power supply fault such as brown- out etc,and it can preset the output voltage for different system.
