Download or read book Design and Evaluation of a Reconfigurable Stacked Active Bridge Dc dc Converter for Efficient Wide Load range Operation written by Rose A. Abramson and published by . This book was released on 2016 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design and implementation of a step-down soft-switched dc-dc converter based on an active bridge topology which overcomes some of the limitations of the conventional dual-active bridge (DAB). The topology comprises a double-stacked bridge inverter, coupled to a recongurable rectifier through a special three-winding leakage transformer. The converter can run in a low power mode that greatly increases light-load efficiency by reducing core loss and extending the zero-voltage switching (ZVS) range. The converter is implemented with a single compact magnetic component, providing power combining, isolation, and energy transfer inductance. The theory of the converter and its various operating modes, referred to in this thesis as the Double-Stacked Active Bridge converter, is also explored, and a magnetic model of the special three-winding transformer and leakage inductance is presented. The target application is for 380 V dc distribution systems for data centers, where the converter operates for the majority of the time at the nominal input voltage, but must have high eciency over a wide load range. A 175 kHz, 300 W, 380 V to 12 V prototype converter achieves 95.9% efficiency at full load, a peak efficiency of 97.0%, an efficiency above 92.7% down to 10% load and an efficiency above 79.8% down to 3.3% load.

Moreover, the widespread use of power electronics enables cost savings and minimization of losses in several technology applications required for sustainable economic growth. The topologies of DC–DC power converters and switching converters are under continuous development and deserve special attention to highlight the advantages and disadvantages for use increasingly oriented towards green and sustainable development. DC–DC converter topologies are developed in consideration of higher efficiency, reliable control switching strategies, and fault-tolerant configurations. Several types of switching converter topologies are involved in isolated DC–DC converter and nonisolated DC–DC converter solutions operating in hard-switching and soft-switching conditions. Switching converters have applications in a broad range of areas in both low and high power densities. The articles presented in the Special Issue titled "Advanced DC-DC Power Converters and Switching Converters" consolidate the work on the investigation of the switching converter topology considering the technological advances offered by innovative wide-bandgap devices and performance optimization methods in control strategies used.
