数字可调式高压直流稳压电源的设计

介绍了以89C52单片机为控制系统的数字可调式直流高压稳压电源的设计和制作.系统包括模拟和数字两部分电路组成,模拟部分主要包括波形发生电路、推挽开关电路、升压变压器、倍压整流电路等;数字部分主要包括键盘接口电路、A/D转换电路、D/A转换电路、显示电路和单片机89C52最小系统电路.模数电路相互配合,很好的解决了以往电路中要求的高精度、低零飘的问题,从而大大的简化了原来的控制电路,降低了成本.

The Design of The Digital Adjustable Direct Current High-voltage Power

The text mainly introduced the process of how to design and make the High-voltage Power Supply controlled by 89C52 single-chip system.The system were composed of the simulate and the digital circuit.The former included square-wave generator,the push-pull switch circuit,the transformer used to promote the voltage,duple-voltage rectifying circuit and so on;the latter included the key system,the A/D and the D/A converter,the display system and the single-chip 89C52 controller.They cooperated with each other,which can solve the problem of high precision and low zero-shift.In this way the control circuit was greatly simplified and the cost was decreased.
