摘 要：本文介绍了半桥LLC谐振变换器的原理，分析了半桥LLC谐振变换器的直流增益曲线。结合目前煤矿磷酸铁锂电池对高效率充电器的要求，设计了采用UCC25600为控制器芯片的LLC大功率磷酸铁锂电池充电器方案，并采用PSIM进行了仿真。开发了实验样机：LLC电源指标25.2V/1000W，可对6单元串联磷酸铁锂电池组充电。仿真与实验结果表明，LLC煤矿磷酸铁锂电池充电器具有效率高，输出电压稳定的优点。

Abstract:
Abstract: This paper introduces the principle of the half-bridge LLC resonant converter,and analyzes bridge LLC resonant converter dc gain curve. Combined with the current mine lithium iron phosphate,which requirements for high efficiency charger,we designe a high-power LLC lithium iron phosphate battery charger using the UCC25600 controller chip, and use PSIM for simulation. We made an experimental prototype: LLC Power Index is 25.2V/1000W, and it can charge six cells in series iron phosphate lithium battery packs. Experimental results show that LLC mine lithium iron phosphate battery charger has high efficiency, stable output voltage.
