摘要：
This study proposes a control method for a dual active bridge (DAB) converter for battery systems to improve loss of light load. The proposed method reduces the circuit gain nonlinearity caused by phase shift control focused on the transformer losses. Therefore, based on calculations through the model of the proposed method and experimental results from load switching, the proposed method is shown to have lower light load loss and better controllability than conventional methods. 2022 The Institute of Electrical Engineers of Japan.
