High-Efficiency Active Switched-Inductor-Based Converter for High Step-Up Application

IEEE Journal of Emerging and Selected Topics in Power Electronics
This article proposes a high-efficiency active switched-inductor-based power converter for high step-up applications. This converter possesses a great voltage ratio, low voltage stress, and high efficiency. It benefits from a transformer in its low current side to foster the voltage gain with minimum winding losses.

High efficiency high step-up converter module for DC microgrid systems

2010 IEEE International Conference on Sustainable Energy Technologies (ICSET), 2010
In this paper, a two-phase dc to dc converter module is first proposed by integrating a forward converter with a voltage-doubler to achieve high step-up ratio and high efficiency. Then, steady state analyses are made to show the merits of the proposed converter. For closed loop control design, the corresponding small signal model is also derived. It is
