Abstract
The development of All Electric Aircraft has provided new opportunities in the area of electronic devices and power electronics. The purpose of this paper is to compare the properties of soft-switching converter topologies when used to achieve dc-dc conversion at high-power and high-voltage levels. The circuit investigated in this paper can operate in a soft-switching manner enabling reduction in device switching losses and therewith an increase in switching frequency. 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 is 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.
