摘要
对DC/DC变换器进行仿真,可更好地指导和改进实际电路的设计调试。但现有仿真软件无闭环仿真模型,针对DC/DC变换器设计很难进行闭环仿真这一问题,本文利用MATLAB软件的Simulink工具箱,结合电路特点,给出环路传递函数,搭建了电路闭环仿真模型,模拟了BUCK电路的环路控制,实现了DC/DC变换器的闭环仿真,为DC/DC变换器的研究与应用提供了理想的工具。同时基于BUCK电路编写了BUCK电路参数的MATLAB设计程序,简化了变换器设计过程。
Simulation of DC / DC converter may guide and improve the design and debugging of actual circuits, but there is no simulation software for closed-loop model. Considering the difficulty of closed-loop simulation of DC/ DC converter, In this paper, combing the circuit characteristics and giving the loop transfer function, the simulink toolbox of MATLAB was used to establish the closed-loop simulation model for simulating the loop control of BUCK circuit and fulfilling the loop simulation of DC/DC converter, which offering an ideal tool for the research and application of DC / DC converter. Meanwhile, MATLAB design program for BUCK circuit parameters was given based on BUCK circuit, simplifying the design of converter.
