Maintenance and optimization of the TCV power supply
Damien Fasel, Ugo Siravo, Jérémie Dubray
The TCV tokamak is powered by a flywheel generator to supply the magnetic coils and the auxiliary heating systems. The generator has just undergone its fourth major overhaul to make it ready for the next ten years, after more than thirty years of almost tr ...
Elsevier Science Sa2024Study of flexible operating conditions in variable-speed hydraulic turbines : advanced models and experimental validation
This PhD thesis is framed within the XFLEX HYDRO project, funded by the European Union's Horizon 2020 research and innovation program under grant agreement No 857832. The ultimate objective of the XFLEX HYDRO project is to increase hydropower potential in ...
EPFL2024High frequency IGCT operation for DC transformer
In spite of the dominance of ac technology for the vast majority of power transmission and distributionsince the late 19th century, the past decades have seen an increase in use of dc electrical power. Inparticular, this has been the case both in high volt ...
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 ...
2022Design of an inverter for high-speed synchronous generators using SiC FETs
Existing inverter designs are not well-suited for use with high-speed generators due to the IGBTs used as switching elements, which are not fast enough. SiC FETs offer a lower switching time compared to IGBTs, which is key to working with high-frequency ma ...
2020Deexcitation Characterization for Power Supply Protection in DC Shipboard Power Systems
The deexcitation of a synchronous machine has been used for the protection of the power supply based on a diode rectifier in marine dc power distribution networks. The fault current from the generator can be eliminated with the protection method utilizing ...
2020Efficient High Step-up Operation in Boost Converters Based on Impulse Rectification
Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera
Conventional boost converters, while having a high level of simplicity and robustness, are known to have poor efficiency at high step-up regime. More complicated topologies have been extensively explored to increase the step-up ratio while keeping a high-e ...
