Abstract :
This paper analyzes the ZVS soft-switching region of a DAB converter with arbitrary operating waveforms. The effect of the junction capacitor of the device and the magnetizing inductance of the transformer are also analyzed. Through the analysis, a group of waveforms for different loading conditions are identified to maximize the ZVS operating region. The results are verified by simulation using real device models.
