摘　　要：数字控制与传统模拟控制相比具有很大优势,是电源发展的一个必然趋势。本文首先对IC3525芯片的闭环控制原理进行简单介绍,之后对IC3525控制的Push-Pull电路进行数学模型推导、以及控制器的算法实现推导,最后利用MATLAB软件搭建了系统模型。仿真结果表明,Push-Pull电路IC3525控制的数字化是可行的。Digital control with great advantages against traditional analog control is an inevitable trend of power development. Firstly, the closed-loop control principle of IC3525 chip is briefly introduced. Next, the mathematical model of Push-Pull circuit with IC3525 control and the controller algorithm are achieved. Finally, the system simulation model is made by using MATLAB software. The simulation results show that the digital Push-Pull circuit controlled by IC3525 is feasible.
