Abstract
The Low Voltage IGCT (3.3kV) is developed to provide a semiconductor able to work at high
switching frequencies (>1kHz), preserving its “high current” capacity (4kA). The ultimate goal is to
increase the dynamic performances of medium/high power converters, thus extending their
application field.
To characterise the experimental samples of 3.3kV IGCTs, an opposition method based test
bench was developed. This method allows the components to be evaluated at different test
conditions in real operation without the need of several megawatt power supplies.
Once the samples were characterised, the applicability analysis of these components on specific
applications related to the French railway network (SNCF) is performed.
Finally, a reactive power compensation application for single-phase systems is studied in detail
and a 100kVAR IGCT based set up is built.

• 3.3 kV IGCT • Medium Voltage • Medium Power

Résumé
Le développement des IGCT Basse Tension (3,3kV) vise un composant capable de travailler à
fréquence élevée (>1 kHz) tout en gardant sa capacité "fort courant" (4kA). L’objectif final est
d’augmenter les performances dynamiques des convertisseurs moyenne/forte puissance et
d’étendre ainsi leur champ d’application.
Pour la caractérisation des échantillons expérimentaux des IGCT 3,3kV, un banc d’essais basé
sur une méthode d’opposition a été développé. Cette méthode permet l’évaluation des
composants sous différentes conditions d’essai en mode de fonctionnement réel sans nécessité
de sources d’alimentation de plusieurs MW.
Une fois les échantillons caractérisés, l’analyse de l’applicabilité de ces composants dans des
applications spécifiques aux réseaux ferroviaires SNCF est abordée.
Finalement, une application de compensation de puissance réactive pour des réseaux
monophasés a été étudiée en détail et une maquette de 100kVAR à base de IGCTs a été
réalisée.
Mots Clefs
• IGCT 3.3kV • Moyenne Tension • Moyenne Puissance

Resumen
Los IGCT de Baja Tensión (3.3kV) se desarrollan para proporcionar un componente capaz de
trabajar a frecuencia elevada (>1kHz) manteniendo su capacidad de “alta corriente” (4kA). El
objetivo final es aumentar las prestaciones dinámicas de los convertidores de media/alta
potencia y ampliar así su campo de aplicación.
Para caracterizar la muestras experimentales de IGCTs 3.3kV, se ha desarrollado un banco de
ensayo basado en el método de oposición. Este método permite evaluar los componentes bajo
diferentes condiciones de ensayo en modo de funcionamiento real sin necesidad de fuentes de
alimentación de varios megavatios.
Una vez que las muestras han sido caracterizadas, se aborda el análisis de la aplicabilidad de
estos componentes en aplicaciones específicas relacionadas con la red ferroviaria Francesa
(SNCF).
Finalmente, se estudia en detalle una aplicación de compensación de potencia reactiva para
redes monofásicas y se realiza una maqueta de 100kVAR con IGCTs.
Palabras Clave
• IGCT 3.3 kV • Media Tensión • Media Potencia

The work presented in this dissertation was carried out in the Static Converters research group of
the Laboratoire d’Electrotechnique et d’Electronique Industrielle, LEEI (INPT-ENSEEIHT-CNRS).
This work takes place as part of a collaboration contract between the LEEI and ABB Switzerland
Ltd. Semiconductors.
After three and a half years of research work, I would like to first thank Mr. Y. Cheron, director of
the LEEI, for accepting me to the laboratory. Next, I would like to express my gratitude to the
advisory committee members of my PhD thesis:
• Mr. Gérard COQUERY, research manager of the New Technologies Laboratory
(LTN) at the French National Institute for Transport and Safety Research (INRETS),
for accepting to be part of my PhD advisory committee.
• Mr. José Ramón TORREALDAY, Professor and department head of the Industrial
Electronics department of the Polytechnic High School at the University of
Mondragon (EPS-MU), Spain. It is an honour to have you as reviewer of my
dissertation and I would like to express my sincere appreciation to you not only as an
exceptional schoolmaster, but also for your personable skills.
• Mr. Francis LABRIQUE, Professor and head of the Electrotechnical and
Instrumentation Laboratory (LEI) of the Applied Science Faculty at the Catholic
University of Louvain (FSA-UCL), Belgium, for the interest shown about my work and
accepting to be a reviewer of my dissertation.
• Mr. Eric CARROLL, Marketing Manager of ABB Switzerland Ltd. Semiconductors,
for his support as one of the main driving forces of this work, for his always much
appreciated comments and for being part of my PhD advisory committee.
• Mr. Hervé CARON, Engineer of the Department of Fixed Installations for Electric
Traction (IGTE) at the French National Railway Company (SNCF), for his
collaboration to this study from the industrial point of view and his participation as a
committee member.
• Mr. Philippe LADOUX, Professor at the Engineering National High School
ENSEEIHT of the Polytechnic National Institute of Toulouse (INPT), head of “Static
Converters” research group at the LEEI and supervisor of this PhD. I would like to
express my sincere gratitude for his wise guidance and support, encouragement and
trust in me. It has been an honour and pleasure to work and share many very good
moments with you. Thank you very much for your friendship.
Throughout the development of my PhD, I have had the opportunity to take part of three different
communities. For the first two and a half years, I shared my time between the LEEI in Toulouse,
France and CIDAE (Power Engineering and Electrotechnologies Research Centre of the
Mondragon University) in Mondragon, Spain, under the frame of a research collaboration
established between both institutions. The last year, I had the opportunity to finish my PhD as an
internship student in the ABB Corporate Research Centre in Baden-Dättwil, Switzerland. I would

like to thank all these institutions for the support to successfully finish my PhD. I would also like to
express my gratitude to the very nice and friendly people that made my work and life more
interesting and easier during these years. In some way, this PhD is also yours.
In Mondragon, I would like to especially render thanks to Professor Mikel Sanzberro for his
teaching and personable skills that stimulated my enthusiasm for power electronics. I will not
forget all the highly valued colleagues (professors, lecturers, assistants, students, etc.) that first
suffered my stay in the “Vehículo Eléctrico” office and then in “GARAIA”: Jose Maria Canales (our
“Channels”), Jonan Barrena (“mi Jonan”), Xabi Agirre (I loved when we were flying together to
Barcelona), Miguel Rodriguez (“del mundo mundial”), Gonzalo Abad, Gaizka Almandoz, Josu
Galarza (“you are the next”), Estanis Oyarbide, Sergio Aurtenetxe, Iñigo Garin (“do not annoy too
much the “abuelo””), Alex Munduate, Agurtzane Aguirre (“I still owe you a “lomo” from
Extremadura, but at least you had some sweet Swiss chocolate”), Raul Reyero, Ion Etxeberria
and his “ladies” Maider, Haizea, Amaia and Elsa, and many others. We had very good times
together. I will always remember you all.
In Toulouse, again, I would like to mention many people that I really appreciate. Amongst them, I
firstly want to give thanks to Professor Henri Foch for his masterful lessons in Power Electronics,
which made me love this topic. I also want to express my gratitude to the professors and
researchers
