The aim of this work is to study the influence of the measurement duration and method on the final DC conductivity estimations...
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.
Open-Delta SBC: a New Converter Topology with Low Number of Sub-Modules for MV applications
This paper aims at giving a contribution to this field by proposing a new converter topology for MVDC applications.
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.
Distributed subsea substation for Offshore Renewable Energy collection architectures and compliance with metal-enclosed switchgear’s normative references
The purpose of this publication is to introduce and assess the operations of the so-called Fishbone architectures from a switchgear point of view.
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
