Descripción del proyecto
Nuevos convertidores para la adaptación a las fuentes de energías renovables
Los esfuerzos de transición hacia fuentes de energía renovables más ecológicas para mitigar el cambio climático han causado numerosas perturbaciones en la red eléctrica, que no estaba preparada. Estos también han dificultado la adaptación a estas nuevas fuentes de energía y a la infraestructura de recarga de vehículos eléctricos (VE). La infraestructura de recarga de corriente continua (CC) ofrece una posible solución para dar cabida a estas nuevas fuentes de energía. Sin embargo, esto exigiría el uso de convertidores CC-CC eficientes, de bajo coste y compactos de baja tensión a media tensión, que actualmente no están disponibles. El equipo del proyecto FOR2ENSICS, financiado con fondos europeos, propone crear estos convertidores utilizando dispositivos de conmutación de voltaje ultraalto basados en carburo de silicio (SiC) y desarrollando y utilizando procesos de producción de bajo coste y alta eficiencia.
Objetivo
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.
