High Gain, Smooth Switching DC-DC Converter Based on Dual Active Bridge Topology

EasyChair Preprint 9085

Abstract

This paper presents the study and development of a bidirectional DC-DC converter powered by current through coupled inductors using phase-shift technique to control the power flow. The original topology, from which this version was conceived, uses pulse-width modulation as the switching technique, but in this work the phase-shift technique is adopted. The proposed modification has the advantage of making the power flow control simpler, and guarantees the operation of part of the switches with soft switching of the ZVS type. The working principle and mathematical analysis of the power characteristic of the converter, as well as its dynamic model are presented. A project example with input voltage, output voltage and power, respectively, of 28V, 180V and 500W is proposed. Simulation results are presented in order to prove the theoretical analysis developed.
