Abstract

SEPIC converter has various applications as a power conditioning system because it has a non-pulsating input current and its voltage can be either stepped-down and stepped-up. However, due to the non-linear characteristics of a this type converter, non-linear control techniques are more suitable to attain better performance in voltage regulation. Due to load and output voltage variations, good performance can be achieved through the Non-linear Control because SEPIC converter is a Non-linear system. The performance of the developed controllers with the SEPIC converter is performed through Matlab environment. The proposed system is suitable for all real-world commercial applications, like the power supplies for medical equipment, computer power supplies, uninterrupted power supplies, etc. Various control techniques such as PI controller, fuzzy logic controller, sliding mode controller are used for analysis using Matlab and results are made to compare. The results are compared for change in load variations
