Wide voltage-range isolated dc-dc conversion for high-power applications
Power electronic converters are becoming more and more important due to the reintroduction of electric vehicles, the increasing use of dc grids in electric transportation systems such as ships and rail vehicles, and renewable electrical power generation including the distribution and storage of energy. Many of these applications require isolated, efficient, and compact converters with a wide voltage range. Within the class of isolated dc-dc converters, the three-phase dual active bridge (DAB) topology is known for its high-power capability, however, the converter is not suited for wide voltage-range applications. In this talk we will discuss a topological variation on the three-phase DAB converter which utilizes multi-level techniques to enable wide-range operation with a high efficiency. The presentation will include a brief introduction on the modelling and modulation of this converter and experimental results, obtained with a 100 kW converter prototype, will be presented.
Nico Baars is currently a PhD researcher at the Electromechanics and Power Electronics (EPE) group in the department of Electrical Engineering at the Eindhoven University of Technology. Prior to joining the EPE group he received the MSc degree in 2013 from Eindhoven University of Technology, Eindhoven, The Netherlands, and the BEng degree in 2010 from the HAN University of Applied Sciences, Arnhem, The Netherlands, both in electrical engineering.
