| 摘 要： | 设计并制作了一个高精度数控直流电流源。数控直流电流源的模拟控制电路部分采用串联反馈式控制方式;以AT89C52单片机为核心辅之以ZLG7289、MAX531、TLC2543、X5045等串行接口芯片构成数字控制部分。单片机实时将预置值和实测值进行比较、调整控制,提高了电流源的输出精度,经实验证明具有较高的控制精度。

| Abstract: | In the project we has designed and made a highly precision Digital-controlled DC Current Source.The analog controlling part of the device uses the serial feedback.The digital part uses AT89C52 as the MCU and serial controlling chips such as ZLG7289,MAX531,TLC2543,X5045.The MCU comparedreal-time the preset value with the measuring results,and adjusted the settings,in order to advanced the output precision of the currentgenerator.It is proved the design had high control precision. |
