摘要
以商用小型DC-DC变换器模块作为高压发生器,研制了一种微型程控高压电源。以数字电位器MCP42010和AT89S52为核心设计了输入电压调节、输出电流检测和故障监测及保护电路。应用程序采用汇编语言和图形化编程语言Labview编写。体积小、重量轻的优点使得该电源非常适用于芯片电泳电导检测等微型检测仪器中。
A portable Programmable high-voltage power supply was developed. Commercial miniature DC-to-DC converters were used as the high voltage sources. Functions of input voltage regulation, output current measurement and overload protection were integrated in one printed circuit board while applications programs were written with assemble language for AT89S52 and graphic programming language labview for PC. The lightness and compactness of the whole device make it ideal for microchip electrophoresis conductivity detector.
