Comparison of controllers in SEPIC DC-DC Converter with high gain

Abstract

Modified SEPIC DC-DC Converter with reduced ripple, High efficiency, Low switch voltage, Low input voltage presented in this paper. The magnetic coupling allows to increase the static gain with reduced switch voltage. Input voltage equal to 12V and efficiency equal to 93% was obtained with magnetic coupling with an output voltage equal to 210V and with feedback efficiency is 96% with an output voltage equal to 290V.
