资料介绍

基于Boost电路作为主电路连接方式,提出一种单电感两路输出DC-DC变换器驱动LED的方法。每条输出通路的电流可独立调节,完成不同用途的多路工作。采用状态空间法对示例电路进行建模,进行小信号分析,导出开环传递函数,绘制伯德图,用PSIM软件进行仿真,验证了系统的稳定性。

Based on Boost circuit, A LED driving circuit was proposed by using the single inductor dual-output method in DC-DC convertor. Each single output circuit current can be independently adjusted, finishing different ways work in different situations. State space averaging way was used to build the mode; the small-signal model was analyzed; the transfer function of the system was gained; the Bode diagram was drawn; the simulation was made by PSIM; the stability of the system was tested and verified.
