摘要
本设计方案本着简单、可靠、功能完备、高精度的原则出发,采用了以单片机为核心部件,由键盘和显示模块、D/A,A/D转换模块,V/I转换和功率放大模块、精密整流模块组成数控直流电源。设计了稳定性较强的电源模块。系统结构较优化,具有较高的控制精度。
Take the simplicity, reliability, all-round function, high precision of this device into account , the program control DC power supply use single-chip microcomputer 89C52 as the center key system, and consists keyboard and display module, digital-analog transformation and analog-digital transformation module, V/I transformation , power magnifier module, and precise commute module. We designed higher stable performance power supply system,has relatively high control precision.
