Materials and Innovative Components for Electrical Engineering (MACIE) is a research axe that focuses on the use of new semiconductor dielectric and magnetic materials to improve the electrical systems performance.

High frequency characterisation of the magnetic materials

High frequency characterisation of the magnetic materials

  • Wide-Bandgap Semiconductors (SiC, GaN, etc.): the new power components based on the Wide-Bandgap Semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) will enable the development of high frequency power converters with high efficiency and high power density. New design approaches of these converters taking into account thermal aspects and electromagnetic compatibility (EMC) need to be developed.
  • Dielectric materials: New insulating materials allow operation at high temperatures and under more severe electrical stresses caused by steeper voltage edges. Solutions will be proposed for the construction of very compact and lighter coils, able to work permanently at high temperatures, but also supporting the steep voltage slopes of the Pulse-Width Modulation (PWM).
  • Magnetic materials: It is also necessary to implement new magnetic materials with characteristics that improve the performance of electrical components through smart design of electrical machines, transformers and ferromagnetic components of the filters based on the development of non-linear models accurate and reliable to represent the electromagnetic and mechanical behavior of these materials.
