Core-less multiphase converter with transformer coupling [PDF]
A coupled multiphase converter where the coupling among the phases is done using core-less planar transformers is presented in this paper. Operating principle of the transformer-coupled converter has been presented previously in the literature and in this paper this concept is applied to develop a core-less converter.

Less-conventional low-consumption galvanic separated MOSFET-IGBT gate drive supply [PDF]
A simple half-bridge, galvanic separated power supply which can be short circuit proof is proposed for gate driver local supplies. The supply is made while hacking a common mode type filter as a transformer, as the transformer shows a good insulation, it

Converter Topologies for MVDC Traction Transformers [PDF]
The paper compares the conventional railway traction systems with new traction systems proposed and developed in the last decade that are also suitable for the medium voltage DC (MVDC) railway electrification concept presented in this project. Differences and requirements of the MVDC traction system will be considered while investigating converter ...
