(Bart is employee DMO) Period: 1 jan dec

7 EMC Studies UT, Structures Strategies for the Improvement of Critical Infrastructure Resilience to Electromagnetic attacks Europese Commissie, 7e kaderprogramma Total budget 4 Meuro. UT: 450k. 8 partners Start: 1 July 2012 PhD researcher: Stefan van de Beek The first EMC law: 1892 Power and communication systems, both using the same return path: interference 14 7

8 15 EU energie reductie plan 40% van totale energie verbruik is electrische energie vermogenselectronica is noodzakelijk om een substantieel deel (geschat wordt: de helft) van de reductie te halen 16 8

9 Smart Grids 17 Maar wat maakt dat netwerk smart 18 9

10 Slimme apparaten Electrolux En slimme interactie

11 21 Technology push ICT, Materials, bijv. Nanocrystalline Maar vooral: Wide bandgap semiconductors (SiC, GaN) Market pull Smart Grid E-Mobility Energy saving LED lighting Wide-range power systems (50-500V,30-300Hz, AC&DC)

12 N Ikeda ISPSD, /13/2012 Efficiency wide-bandgap materialen Weerstand Si, SiC en GaN: Maar ook VEEL SNELLER : meer storingen 23 Maar market pull van nieuwe technologie zal resulteren in
