Blocking-Cap-Based DAB Converters
2018Blocking-cap-based dual active bridge (DAB) converter with wide voltage conversion gain is studied in this chapter. The DC blocking capacitor, which is used for avoiding the DC flux bias in the transformer of conventional DAB converter, is utilized to achieve better performance under wide voltage gain range.

A Novel Converter Integrating Buck-Boost and DAB Converter for Wide Input Voltage
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020Dual active bridge (DAB) converters are widely used in new energy electric vehicles. However, the traditional DAB converter has limited soft-switching range and high circulating currents under wide input voltage especially when both-side voltages are mismatched. As a result, large power loss and low efficiency are undesirably obtained. In this paper, a

High-Efficiency DAB Converter Using Switching Sequences and Burst Mode
IEEE Transactions on Power Electronics, 2016Dual active bridge converters enable bidirectional power flow in buck and boost operating modes. This paper presents an advanced switching sequence and burst-mode strategy to balance conduction, switching, and magnetic losses under light, medium, and heavy loading conditions, leading to improved operating efficiency. The implementation of the switching
