Dual-coupled inductor-fed DC/DC converter for battery drive applications

Abstract

A new isolated boost dc-to-dc converter suitable for a low-input-voltage application is introduced. The proposed converter features low switch current stresses, wide range of input voltage, and inherent inrush current protection, essential for the design of a low-to-high-voltage conversion circuit. A comparative analysis and experimental results are resented to show the validity of the proposed converter.
