Combined Non-Isolated High Step-Up Boost Converter And Sepic Converter Applied To Induction Motor
A general Boost converter has a disadvantage that it has limited voltage step-up ratio because of its parasitic
resistance and also for high voltage applications it requires a high voltage rating diode which causes serious reverse recovery
problems, which results in low step up ratio and low efficiency, so a non-isolated high step-up boost converter combined
with an isolated sepic converter is developed in this paper to satisfy both high efficiency and high conversion ratio which
does not need a current snubber for the diodes and is applied to an induction motor using MATLAB platform.
