A Versatile DC-DC Converter for Energy Collection and Distribution using the Modular Multilevel Converter
Alfred Rufer, Drazen Dujic, Michail Vasiladiotis, Stephan Kenzelmann
The drawbacks of conventional Modular Multilevel Converters (MMC) are described in terms of short-circuits. The configuration of MMC-transformer-MMC proves to handle short-circuits at the input and output without the need for additional DC or AC circuit br ...
Ieee2011Comparison Between the Behavior of HTS Thin Film Grown on Sapphire and Coated Conductors for Fault Current Limiter Applications
The major drawback for the commercialization of fault current limiter (FCL) made of YBCO on sapphire is their expensive price. In the recent years, coated conductors (CC) have been extensively developed and, due to their lower prices, have been recently te ...
Institute of Electrical and Electronics Engineers2009Controlled Resonant Circuit with Commutated Capacitors using Self-Switching Power Devices
Alfred Rufer, Daniel Siemaszko, Christian Rod
This paper presents a preliminary work on a resonant circuit, also called AC-dipole. The resonance frequency of the circuit is changed by the mean of a variable capacitor connecting an inductor. For this purpose, a bank of switched capacitors of different ...

Power Factor Corrected rectifiers are a new tendency in development of power supplies. In the last few years, a lot of R&D activities have led to a new category of products for one-phase applications. In this contribution, a new simplified topology is prop ...
20053D Finite Element Simulations of strip lines of a YBCO/Au Fault Current Limiter
Francesco Grilli, Joseph Duron, Bertrand Dutoit
Geometrical aspects of the design of fault current limiters (FCL) have a great impact on their performance. Recently, the University of Geneva have presented optimized geometries obtained by splitting the FCL into many small dissipative lengths in order to ...
2005JORDI, a test facility for measurement of contact resistance distribution in full-size conductor terminations
A new test facility, dedicated to the measurement of contact resistance distribution in full-size conductor termination, has been designed and manufactured at CRPP Fusion Technology in Villigen, Switzerland. The facility will be used to characterize and qu ...
2004Investigation and control of a hybrid asymmetric multi-level inverter for medium-voltage applications
Power-electronic inverters are becoming popular for various industrial drives applications. In recent years also high-power and medium-voltage drive applications have been installed. However, the existing solutions suffer from some important drawbacks. Hyb ...
EPFL2003Enhancement of power system transient stability using superconducting fault current limiters
Bertrand Dutoit, Marten Sjöström
Transient stability investigations consist of studying the rotor oscillations of generators (electro-mechanic oscillations, 0.1-2 Hz) after the occurrence of a fault of large amplitude, e.g. short circuit. The goal is to indicate if the generators are capa ...
