基于UC3845的单端反激电路设计与仿真
资料介绍
通过分析单端反激电路的工作原理,提出了一种双路低电压输出系统的设计方案。对功率变换电路、输出回路、输入回路和高频变压器等进进行分析设计。并且采用UC3845控制芯片采用电压和电流双环的控制方法设计控制电路。最后使用MATLAB仿真软件建立了仿真模型,输出均达到了要求,纹波较小,表明设计可行,为系统的应用提供参考。
By analyzing the working principle of the single-end flyback circuit,a design scheme of a two-channel low-voltage output system is proposed.The power conversion circuit,output circuit,input circuit and high frequency transformer are analyzed and designed.The UC3845control chip is adopted to design the control circuit by the double loop control method of voltage and current.Finally,the simulation model is established by using MATLAB simulation software.The output reaches the requirements,and the ripple is small,which indicates that the design is feasible and provides a reference for the application of the system.
