SuperGrid Institute wins 4 new European projects!
SuperGrid Institute has been extremely successful within the Horizon Europe framework, winning 4 project bids it submitted to the European Commission.
Test Systems and Models for DC/DC Converters intended for DC Transmission Grid Applications
The paper reports on the development of two 600 MW test DC-DC converters in the CIGRE B4.76 working group.
Medium Voltage Diode Rectifier Design for High Step-Up DC-DC Converter
A medium voltage rectifier, relying on series connection of SiC Schottky diodes, is designed and tested within a unidirectional isolated DC-DC converter.
Experimental study of the reduction and removal of turn-on snubber and its limiting di/dt clamp inductor for IGCT based MMC submodule using fast silicon diodes
The goal of this study is to determine if the snubber can simply be removed in IGCT if fast enough freewheeling diodes are used.
DC-MMC with reduced number of sub-modules providing fault blocking capability in HVDC Grids
This paper proposes to use a main switch instead of adding sub-modules in the topology to provide fault blocking capability.
Unidirectional step-up isolated DC-DC converter for MVDC electrical networks
This article focuses on the DC-DC converter for MVDC electrical networks. A classification of DC-DC converters is proposed.
Series connected SiC-MOSFETs voltage balancing: two methods with adaptative delays
This paper presents different embedded measurement techniques in an active gate-driver that adjusts switching delay in real-time.
Design of a test package for high voltage SiC diodes
A custom package for SiC diodes is presented.
Design Methodology Based on Prebuilt Components for Modular Multilevel Converters with Partial Integration of Energy Storage Systems
We propose a novel design methodology for these converters considering they are built based on existing prebuilt submodules.
