EMC and earthing concept of the ITER EC-system
Damien Fasel, Ugo Siravo, Jérémie Dubray, Francisco Sanchez
Gyrotrons and High Voltage Power Supplies (HVPS) used on electron cyclotron (EC) systems are the source of large electromagnetic interference (EMI). Arcing events inside gyrotrons is the most frequently cited issue, but fast shutdown of a HVPS can produce ...
ELSEVIER SCIENCE SA2023Flexible High Power Electronics Solutions for Hydro-Power Applications
The current global energy landscape is characterized by an increasing demand for affordable and sustainable energy sources, leading to an ever increasing integration of intermittent renewable energy resources into the grid. The intermittent nature of these ...
EPFL2023Homogenous power distribution along gyrotron collector walls
Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Ugo Siravo, Jérémie Dubray, Miguel Filipe Silva Füglister, Pierre-François Isoz
EC RF power sources will play a major role in the future operation of large scale tokamaks (ITER, DEMO). A 1MW/170GHz gyrotron is the standard RF power unit considered for ITER. Even though the efficiency of such devices has been significantly increased th ...
2023Measurement of WBG-based power supplies
Elison de Nazareth Matioli, Hongkeng Zhu, Armin Jafari
This paper discusses different measurement methods to evaluate the efficiency of WBG-based power supply solutions, including electrical measurement methods and their verification with calorimetric methods, and compares the performance of Si-based and GaN-b ...
New York2023Hybrid Modular Multilevel Converter for Pumped Hydro Storage Applications
Energy balance in a power system must be maintained at all times, regardless of the variations in generation and consumption. Large Pumped Hydro Storage Plants (PHSPs) are introduced to the power system to accumulate the excess of energy during the low dem ...
EPFL2022Multiobjective Vector Modulation for Improved Control of NPC-Based Multi-Source Inverters in Hybrid Traction Systems
The concept of a multi-source inverter (MSI) based on NPC topology was recently introduced for hybrid-electric powertrains to connect several dc sources to the traction load in a single conversion stage without magnetics. This work proposes a new modulatio ...
2022Data-driven Power Electronic Converter Control Design in Power System Applications
In recent years, power systems have evolved in physical and cyber-physical layers. In the physical layer, the changes are motivated by environmental concerns resulting in the integration of new types of generation/demand/storage into the grid. These integr ...
EPFL2022Direct Current Transformer Impact on the DC Power Distribution Networks
Drazen Dujic, Renan Pillon Barcelos
The latest developments in dc transformer technology are enabling larger and more complex dc power distribution systems. However, the literature is scarce regarding the investigation and quantification of its impact on the dc grid. Therefore, this paper an ...
