摘要
介绍了基于MSP430单片机的数控双极性直流稳压电源的设计方法,从软、硬件两方面阐述了系统各部分组成和工作原理。系统以MSP430F149单片机为控制核心,根据设定值输出所需电压。同时,检测输出电压,利用闭环回路,对输出电压进行精密的自动跟踪调节。另外,对负载电流进行监测,实现过载保护和显示报警。
A kind of design in the dual polarity DC regulated source based on microcontroller was introduced,this thesis expatiated the composing of system and function from software and hardware. The system take MSP430F149 as the control plat- form, output voltage by setting. More than that, re- covery through the formation of the closed - loop control to achieve high- precision autotracking ad- justable function. , supply current can be real - time monitored by microcontroller. In addition, overload protection and alarming was implemented.
