摘要
在对LLC与LCC两种拓扑比较的基础上,介绍了LCC拓扑的特点,采用英飞凌的高集成度控制器ICL5101实现了1个120W的LCC恒流LED驱动电源,进行了输出特性的实际测试,测试结果证明LCC拓扑可以在较窄的频率变化范围内,实现极宽的输出电压及电流调节。
Based on the comparison of LLC and LCC, this paper introduces the feature of LCC topology, realizing a 120 W LCC constant current LED drive power with Infineon＇s high-integrated controller ICL5101. An actual test of output performance is conducted, whose result shows that LCC topology can realize wide output voltage and current regulation within a narrow frequency variation.
