摘要
为提高LED驱动电路的使用寿命并优化其整体性能,提出了一种新型的基于CUK电路的非隔离型AC-DC电路拓扑。该拓扑通过在基本的CUK电路上增加一个MOSFET来实现。可实现高功率因数并消除电解电容。对于该结构进行了详细分析,并且使用LTspiceIV软件对其进行了开环和闭环的仿真,最后通过带载实验来证实分析的正确性。
In order to improve the lifespan of the LED driver and optimize its overall performance, this paper presents a novel non-isolated AC-DC converter based on CUK converter. The topology is implemented by adding a MOSFET to the basic CUK converter. In this paper, the structure is analyzed in detail and the LTspiceIV software is used on the open loop and closed loop simulation. Finally, the correctness of the analysis is verified by experiment.
