摘要

本文详细分析了用于驱动led的单级AC/DC非隔离变换器的几种拓扑结构。这些拓扑结构可实现高功率因数和稳压。这些转换器设计为交流输入230V，直流输出48V，开关频率为20KHZ，负载为200W。在MATLAB/SIMULINK软件上对拓扑结构进行了实现和比较。

Analysis and design of non-isolated single phase AC/DC PFC topologies to drive LEDs

This paper presents a detailed analysis of several topologies of single stage AC/DC non isolated converters used as a power supplies for driving LEDs. High power factor and regulated voltage is achieved with these topologies. These converters are designed with 230V AC input, 48V DC output for 200W load at switching frequency of 20KHZ. Implementation and comparison of topologies are done on MATLAB/SIMULINK software.
