摘要
介绍基于MSP430单片机的开关稳压电源的系统结构和总设计方案。该设计硬件电路由整流滤波电路、升压斩波电路、PWM驱动电路及保护电路组成。该系统的软件是在IAR Embedded Workbench开发环境下采用C语言编写,主要包括12位高精度A/D采集、PWM驱动电路、过流保护等模块的设计,同时具有键盘设定、液晶显示实时等功能。
This pape introduces a system structure of switching power supply based on MSP430 single chip computer and a total design project. The hardware includs load resistance of rectifier -filter circuits, boost chopper circuit,PWM driving circuit and protection circuit. The software adopts C language writing,to complete some designs of high precision A/D data acquisition of 12 bit,overload protection,in the meantime,it has the functions of setting of keyboard and display of real -time value.
