Power Factor Improvement by Using Modified Sepic Converter

Abstract

DC to DC converters are the electronic devices used to step up or step down the DC voltage level, whenever the equipment fails to operate at maximum efficiency. If a electrical device as a power factor less than one, that means more input current must be supplied for a given output power dissipation and more powerful source is required to deliver the required output power.

The main objective of this project is to improvement of power factor of the system by using MSEPIC converter and also the theoretical and experimental (simulation) results with the MSEPIC converter are comparing with the classical boost converter topology by using MATLAB software.
