Numerical investigations of ReBCO conductors with high limitation electric field for HVDC SFCL
Superconducting fault current limiters (SFCL) are already in operation in alternative current medium voltage applications and their use in HVDC grids is very promising due to their capability of reducing high short-circuit currents.
A novel hyperbaric vessel for SuperGrid Institute
Since 2016, SuperGrid Institute’s program 4 has intensely worked on the specification of a test platform with the capability to go up to 40bars of internal pressure and validate subsea node, a SuperGrid Institute concept for offshore meshed networks. Beside its imposing size, the particularity of this platform is that it allows combined testing functions on subsea high-voltage cable systems including water pressure, di

PhD William LEON GARCIA “Protection strategy for HVDC networks”
Multi-terminal high voltage direct current (MTDC) grids, or supergrids, are considered an interesting solution to integrate large amounts of renewable power and release congestion of existing AC power grids. Nonetheless, safe and reliable operation of such grids require the development of new DC protection systems.

Comparison between numerical and analytical methods of AC resistance evaluation of medium frequency transformers : validation on a prototype
In the future, medium-frequency transformers (with a frequency range of 5-100 kHz) will be major components in dc-dc converter applications, for both medium-voltage direct current and high-voltage direct current networks.
Analysis of voltage and current unbalance in a multi-converter topology for a DC-based offshore wind farm
High Voltage Direct Current (HVDC) is increasingly being used for electric power transmission over long distances.
State of the art of gate-drive power supply for medium and high voltage applications
Gate-drive power supplies in medium voltage and high voltage direct current (MVDC / HVDC) applications require medium to high voltage insulation.
