基于MATLAB的BUCK电路设计与仿真

Design and Simulation of BUCK Circuit Based on MATLAB

利用对电路的仿真设计,使得对BUCK电路的调试与设计更加的简单与容易。本文主要研究DC/DC变换器,对BUCK电路的基本工作原理进行了概括性的阐述,并且设计了电路的元件参数。搭建了BUCK电路的闭环仿真模型,使其在MATLAB的SIMULINK里进行仿真,模拟了BUCK电路的PID环路控制最后用仿真的结果来验证我们设计的参数是否正确。从而使得对DC/DC变换器的研究更加简单跟直观。

In order to improve the design and debugging of the BUCK circuit, the circuit can be simulated by software. This paper studies the DC/DC converter, describes the working principle of the BUCK circuit, and the circuit parameters of the components are designed. Using MATLAB software, Simulink toolbox, build open and closed loop BUCK circuit simulation model, simulation of the open loop and PID loop control circuit BUCK. And two kinds of simulation model were compared. The results show the correctness of parameter design, research and application of DC/DC converter provides an ideal tool.
