A Method for Detecting DC Bias in Transformer of Dual Active Bridge DC-DC Converter
2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021 A potential concern with the isolation transformer in a dual active bridge DC-DC converter (DAB) unit is the DC bias of magnetization. With the influence of DC bias, the loss of the transformer increases, and the lifespan decreases. However, it is difficult to accurately measure the small DC component mixed in a large (>10A peak), high-frequency AC ...

DC Bias Study for DC-DC Dual-Active-Bridge Converter
2018 IEEE 4th Southern Power Electronics Conference (SPEC), 2018For the dual-active-bridge (DAB) converter, the adoption of high-frequency transformer provides galvanic isolation, but also brings the possibility of dc bias. In this paper, the calculation methods for dc bias are derived in details. Hence, the dc bias magnetizing current can be predicted considering the inconsistency of semiconductor switches and ...
