Abstract
This paper presents a three phase dual active bridge(DAB) topology as the most convenient topology for high power-density DC/DC converters for railway applications. The three-phase DAB is analyzed concerning the current modes, output power and soft-switching region, including the effect of zerovoltage switching(ZVS) capacitors. Furthermore, two methods are discussed, aiming to extend the soft-switching region, since no-load conditions in the entire operating range are required. A prototype design is made, in which optimal component values are calculated, to minimize losses. Finally, a prototype is built with the required specifications, resulting in an efficiency of 95.6% at 80kW of output power.
