Description du projet
De nouveaux convertisseurs pour une meilleure adaptation aux sources d’énergie renouvelables
Les efforts de transition vers des sources d’énergie renouvelables plus vertes pour atténuer le changement climatique ont provoqué de nombreuses perturbations sur le réseau électrique qui n’y était pas préparé. Ces efforts ont également compliqué l’adaptation à ces nouvelles sources d’énergie et l’infrastructure de recharge des véhicules électriques (VE). L’infrastructure de recharge en courant continu constitue une solution potentielle pour accueillir ces nouvelles sources d’énergie. Cependant, cela exigerait l’utilisation de convertisseurs DC/DC efficaces, peu coûteux et compacts pour le passage de la BT à la MT, qui ne sont pas disponibles actuellement. Le projet FOR2ENSICS, financé par l’UE, propose de développer ces convertisseurs en utilisant des dispositifs de commutation à ultra-haute tension basés sur le carbure de silicium (SiC) et en développant et utilisant des processus de production peu coûteux et à haut rendement.
Objectif
Driven by the continued effort to combat the climate change and achieve carbon neutrality, the composition of the energy sources and consumers connected to the electrical grid is rapidly changing. An increasing amount of issues are being experienced by distribution system operators while trying to accommodate new systems like renewable energy sources or electric vehicles charging infrastructure. One of the possible solutions is to develop a DC distribution infrastructure, which is especially interesting as most of the new connections mentioned above are native DC sources and loads, respectively. This requires low cost, very efficient and compact DC/DC converters from LV (<1500V) up to MV (>10kV). However, currently no commercial solutions exist on the market. The aim of this project is to develop and demonstrate a commercial DC/DC converter prototype which can be introduced to the market within short timescale (<3 years) after completion of the project. To achieve such an ambitious target, the project team has decided to focus on the development of ultra- high voltage (UHV) SiC based switching devices which would allow for a remarkable simplification of the converter topology as well as a very compact design when coupled with high frequency operation. For this purpose, the project aims at the design, fabrication and testing of 15 kV SiC IGBTs modules. The choice of the device technology is based on previous studies, which point towards a break-even voltage between SiC MOSFET and SiC IGBT just above 10 kV. Highly relevant, both cost and environmental impact reduction of the fabrication processes will be targeted, using novel approaches for material growth and semiconductor processing. At the same time, another major target of the project is to understand reliability issues affecting different converter components such as UHV switching devices, passive components, and medium frequency transformer associated with high switching frequency and high voltage environment.
