摘要
文章主要讨论在频域下对变换器补偿网络的设计问题,为非理想Buck电路设计了电压型补偿网络,并通过MATLAB软件对开关变换器系统的开环传递函数进行了分析,并用simulink搭建了电路模型,比较了在开环和闭环两种情况下负载和输入电压扰动时输出电压的波形,得出了较为理想的结果,给变换器的环路设计提供了参考。
This paper mainly discusses the design of compensation networks for switching converters in frequency domain. Compensation networks of voltage mode are made for nonideal Buck converter. The transfer function of the networks is analyzed with MATLAB, and then the circuit model is verified with simulink. Comparing the outcomes of open loop sys tem and closed-loop system with compensation networks, the results turned out to be in accordance with the theoretical analysis. This paper provids reference to loop circuit design of switching converter.
