Abstract

This paper presents the regulation of the output voltage and inductor currents in a Single Ended Primary Inductor Converter(SEPIC), operating in the continuous conduction mode (CCM) using a sliding mode controller. Owing to the time varying nature ofthe SEPIC converter, designing a feedback controller is a challenging task. In order to improve the dynamic performance of theSEPIC, a Sliding Mode Controller (SMC) is developed. The developed SMC is designed by using a state space average model. Theperformance of the developed controller with the SEPIC converter is validated at different working conditions through Matlabsimulations. It is also compared with the performance while using a PI controller. The results show that the designed controller givesvery good output voltage regulation under different operating conditions such as a varying input voltage, changes in the load andcomponent variations. A 48V, 46W experimental setup for has been developed in an analog platform to validate the performance ofthe proposed SMC.
