Abstract :
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.
