摘要
数字电源的开发是电源的发展趋势,有着更加灵活的控制性能,更加稳定的系统输出,并且可以防止系统老化等诸多优势。文中以数字电源系统结构为基础,使用MATLAB这一功能强大的数学处理工具,分别完成了DC/DC变换器,PID(比例、积分、微分)控制算法以及数字式脉冲宽度调制技术(DPWM);接着利用MATLAB的绘图功能,在对DC/DC变换器主结构与反馈回路进行系统联调后,清晰地给出了控制算法的实现效果图,为数字电源算法的验证及其程序化搭建了一个简捷明了的平台。
The development of digital power supply has becoming a trend of power supply, which has a more flexible control performance, a more stable system output, and an advantage of preventing system aging. In this paper, on the basis of the digital power system structure, a DC / DC converter model , Proportional, Integral and Derivative (PID) control algorithm and Digital Pulse Width Modulation (DPWM) are realized by MATLAB. After combined adjusting of the main structure and feedback loop of DC / DC converter, the graph of digital power control algorithmt is clearly given by using graphic function in MATLAB. This work provides a simple and an effective platform for the verification and program of digital power supply.
