数字式开关电源控制技术建模研究

摘要

A digital switching power supply control technology is proposed, which is applied to improve traditional analog switching power supply control accuracy and response speed. This paper takes DC/DC converter as the object of study to analyze the advantages of digital switching power supply, relies on buck digital switching power supply to establish a mathematical model,uses Matlab to model this digital switching power supply system and debugs the PID controller parameters step by step. The simulation results show that this system control technology is feasible.%针对传统模拟式开关电源控制精度、响应速度等性能难以提升的问题,采用数字式开关电源控制技术.以DC/DC变换器为研究对象,分析数字式开关电源的优势所在；依托Buck型数字式开关电源,建立数学模型；在MATLAB上建立数字式开关电源系统模型,并分步调试选取PID控制参数,验证了系统控制技术的可行性.
