DC-DC converters with galvanic isolation are a key element in the aircraft DC\ndistribution system and Dual and Triple Active Bridge converters are one of the\nmost interesting candidates in this application. The high-frequency transformer\nleakage inductances play a key role in the AC Link of these converters. This\nleakage inductances determine the power transfer capability of the converter\nand shape the AC link currents. The leakage inductance value is related to the\ndistribution of the transformer windings and it changes with the RMS value of\nthe AC link current. In this paper, first a high frequency transformer is\ndesigned for a Dual and Triple Active Bridge converter for the More Electric\nAircraft DC power system. Then, an Ansys/Maxwell Finite Element analysis is\nperformed on the leakage inductances of the transformer in three different\nwinding configurations and in different AC link RMS current values. Finally,\nthe transient performance of the design is validated by the Ansys/Maxwell\nTransient.\n
