P.Sridhar, P.Arulkumar

The aim of this study is to develop an high-efficient single-input multipleoutput dc–dc boost converter. The proposed converter can boost the voltage of a low-voltage input power source to a controllable high-voltage dc bus and middle-voltage output terminals. The high-voltage dc bus can take as the main power for a high-voltage dc load or the front terminal of a dc–ac inverter.Moreover, middle-voltage output terminals can supply powers for individual middle-voltage dc loads or for charging auxiliary power sources (e.g., battery modules). In this study, a coupled-inductor based dc–dc converter scheme utilizes only one power switch with the properties of voltage clamping and soft switching, and the corresponding device specifications are adequately designed. As a result,the objectives of an high-efficient power conversion, high step up ratio, and various output voltages with different levels can be obtained. Some experimental results via a kilowatt-level prototype are given to verify the effectiveness of the proposed an efficient SIMO dc–dc boost converter in practical applications.in this dc dc converter we verified in simulation output wave form using matlab software.
