摘要
介绍了一种基于PIC16F877单片机的开关电源的设计。该电源把结合单片机自动测控技术,采用传感器进行数据采样,采用PID控制算法进行电压自适应调整和电路保护。以电力机车用110 V开关电源为例,给出了整体硬件电路、系统的控制算法及软件流程,并对电源进行建模实验,得到了与设计要求相符合的结果。
The design of a switching power Supply based on PIC16F877 single-chip was introduced. This power supply combines auto-test and control technology of single-chip, adopting sensor to carry out data sampling, adopting the PID control algorithm to carry out voltage adaptive adjusting and circuit protection. Take 110 V switching power supply by electric locomotive as an example, giving out the integrated circuit and control algorithm of system as well as software flow. At last the result according with design requirements was achieved by modeling on the designed power supply.
