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. I...
