A Smart Modeling & Simulation of the Single Ended Primary Inductor Converter (SEPIC)

The paper presents how to design the single ended primary inductor converter (SEPIC) with the smart modeling. Two separated inductor of the converter operates with higher boost ratio compared with a standard boost power converter for the improved performance. The power circuit of the converter is more spurious than the standard boost converter due to presence of the reverse recovery effects across the SEPIC diode so the switching transients is ably optimized by the designing aspects and competent the control course of the action to haven the power switches and to improve the performance of the SEPIC converter.
