PROJECT TITLE :

High-Efficiency Step-Down Converter ViaCoupled Inductor - 2016

ABSTRACT:

In this study, a high-efficiency single-input multiple-output (SIMO) step-down converter is designed. The coupled-inductor-based SIMO step-down converter utilizes two power switches with the properties of voltage clamping for the middle-voltage switch, and soft switching for all power switches because of the appropriately choice of the corresponding device specifications. Thus, the leakage inductor energy of the coupled inductor can be recycled, and the voltage spikes on power switches can be alleviated. Moreover, the switching losses can be considerably decreased as a result of of all power switches with zero-voltage-switching (ZVS) options. So, the objectives of high-efficiency power conversion, high step-down ratio, and numerous output voltage with completely different levels will be obtained. The effectiveness of the proposed SIMO step-down converter is verified by experimental results of a converter prototype in sensible applications.
