基于煤矿井下对LED驱动电源的本质安全要求,研究并设计了一种本安型大功率LED驱动电源。采用单端反激变换器作为该设计的拓扑结构,通过对恒流工作状态下变换器的原理及静态特性进行分析,给出了同时满足输出纹波电流指标和本质安全要求的电感、电容参数设计方法,通过Sa-ber软件仿真及试验验证,得出本安大功率LED驱动电源理论设计是正确的。

According to the intrinsic safe requirements of the LED driving power sources applied to the danger sites in underground mine, an intrinsic safe type larg e power LED driving power sources was researched and designed.The single-end flyback converter was applied to topology structure of the design.With the analysis on the principle and the static features of the converter under the constant current working conditions, the design method of the inductance and capacity parameters to me et the requirements of the output ripple current index and intrinsic safe was provided.With the Saber software simulation and the test verification, the correction of the t heoretical design for the intrinsic safe and large power LED driving power was obtained.
