Comparative Analysis Of Topologies Used In SEPIC Converter For Power Factor Correction

Expensive use of power electronic devices in various applications of power system which could result in power quality issues like low power factor, high THD, high electric stresses and complexity in cascaded connection. In order to overcome the above problems, there is a need to operate converter at unity power factor. In this work, a new modified multiplier SEPIC PFC topology is proposed and Comparative analysis has been carried out with conventional single stage SEPIC PFC topology. The performance of proposed topology can be Inspected by carrying simulation in MATLAB environment with PI and PID controller. The obtained results justice effectiveness of proposed work.
