Theoretical and experimental analysis of the soft switching process for SiC MOSFETs based Dual Active Bridge converters
In the new electrical grids, series/parallel converters architectures can be considered for medium and high voltage power conversion. Dual Active Bridge (DAB) topology is a serious candidate to be implemented within these converters.
Overview of DC-DC Converters dedicated to HVDC Grids
This paper presents an overview of the DC-DC power converters dedicated to HVDC proposing a classification based on their structure.
PhD Benoît TEZENAS du MONTCEL “Experimental study and modelling of a metal vapor plasma in a vacuum chamber for the development of High-Voltage Circuit Breakers”
The study involves first the building of an experimental setup where arcs, created between two fixed CuCr25 contacts, were visualized using a high-speed camera in a vacuum demountable chamber.
MVDC DC-DC CONVERTER TECHNOLOGY – The building block of future MVDC grids
This poster describes the DC-DC converter technology intended for Medium Voltage Direct Current grids. The benefits of the proposed technology are highlighted for the DC collector for offshore wind farms.
Design of a 4-Phase Intercell Transformer Converter for a Space Charge Measuring System
This paper presents the design of a power electronics converter to produce strong current pulses (about 400A) in the core of a HVDC cable in order to use the thermal step method to evaluate the ageing state of the dielectric component. The described converter uses a magnetic coupler with intercells transformers and is current controlled. Index Terms—magnetic coupler; intercell transformer; high current pulses; thermal step method; dielectrics.
