Split-Capacitor Dual-Active-Bridge Converter

IEEE Transactions on Industrial Electronics, 2021
In this article, a split-capacitor (SC) dual-active-bridge (DAB) converter is proposed. In the proposed converter, dc-link capacitors in both the input and output are split, and primary and secondary windings of the transformer are connected to midpoints of the input and output dc links, respectively.

Complete ZVS Analysis in Dual Active Bridge

IEEE Transactions on Power Electronics, 2021
Zero-voltage-switching (ZVS) has been widely applied in widebandgap devices based on high-switching-frequency converters, for instance, dual-active-bridge isolated dc–dc converter, which consists of two H-bridges. To secure ZVS for all eight switches, previous literature mostly focuses on half-bridge to analyze switching transitions, which, however, is

Dual active bridge buck-boost converter

2009 IEEE Energy Conversion Congress and Exposition, 2009
A novel isolated bidirectional dc/dc converter suitable for high power applications is proposed. The proposed converter has bidirectional power flow capability with low device ratings for a wide source voltage range. The converter is controlled by varying the duty cycle and phase of the firing pulses, to achieve power flows in both directions and ...

Dual Switching Frequency Operation of Dual Active Bridge Converter

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper presents a dual switching frequency (DSF) control method for the dual active bridge (DAB) converter to operate the primary-side and secondary-side full bridges with two different switching frequencies. In the DSF control, the switching frequency of active switches at the secondary side is halved via alternately retaining and skipping the ...
