摘　　要：相对于3G和4G通信,5G通信具有超高速率、极低延时等特点,因为5G通信需要更大的电源功率。本项目采用半桥LLC电路作为主拓扑结构,高效的LLC变换主回路的参数设计方法,使得电路具备自钳位功能,不容易引起灾害。经过验证,系统能够将高压交流电功率转换成可变电流和可变电压的直流电功率,降低了损耗。Comparing with 3G and 4G technology,the 5G tech is higher speed and lower latency,therefore the 5G application needs more power than ever.This project is based on half bridge LLC topology with dedicate designing of parameters to get a self clamp function,so it is more reliable and safety.After testing,this power system can convert high voltage AC to target DC in CV or CC mode with a very low Power self consumption.
