摘要 首先介绍了高压直流开关电源的现状及发展情况,研究了高频开关电源的基本原理,设计出一种实用的高压直流开关电源系统。整个电源系统以89C52单片机作为控制核心,将输出电压,电流采样,经过单片机内由软件编程构成的数字PI调节器处理后控制输出电压的变化。并设计了过压和过流保护功能,应用LED数码管显示输出电压、电流值。 The actuality and development of high voltage direct current switch power supply is introduced in this thesis firstly, it investigates the basic principle of high frequency power supply and designs a practical high voltage direct current switch power supply system. The whole pow- er supply system takes 89C52 SCM as control kernel, sampling the output voltage and current. The voltage and current are sent to digital PI ad- juster in the SCM structured with pr6~ramming, the output signal of PI adjuster control the power supply output voltage. The system owns protec- tion function , using LED shows output voltage and current. To validate the feasibility of design of the system, MATLAB is used for simulation. Finally, the system is debugged in practice.
