Modulation strategy to operate the dual active bridge DC-DC converter under soft switching in the whole operating range
TL;DR: In this paper, a new modulation strategy that allows operating the dual active bridge (DAB) dc-dc converter under soft switching in the whole operating range is proposed, which is ruled by imposing a certain modulation index in one of the two bridges and a phase shift between the transformer primary and secondary voltages.

A comparison of high power DC-to-DC soft-switched converter topologies
TL;DR: In this paper, the authors compare the properties of several soft-switching converter topologies when used to achieve DC-DC conversion at high power and high voltage levels, and show that the switching frequency can be significantly higher than obtained using GTO devices, leading to smaller, lighter weight, and potentially more cost effective equipment.
