Prof Basler centre discusses the surgecurrent robustness of new SiC MOSFET chip technologies with two PhD students at a test bench in the TU Chemnitz drives in industry or where costs are a big issue such as in mass market EVs with moderate drive power There are also possibilities in hybrid technologies combining silicon carbide to ensure low losses for light load conditions with the beneficial I-Vcurve of Si bipolar devices at higher currents This is under discussion for EV applications Further there are already multilevel power modules on the market combining the advantages of IGBTs at positions with lower switching frequency and SiC MOSFETs for positions needing higher switching frequency Improving capacity and yield As noted investment in new fabrication plants and increasing the yields per wafer are important in boosting the supply to meet mushrooming global demand In this respect there are investments and advances in manufacturing silicon carbide but in the case of SiC important work is also being done in splitting technologies to use the raw wafer for more than one processing run A 1200 Vclass SiC chip only needs to be 10 µm thick but ease of handling in the fab needs it to be 10-or 20-times as thick and a raw 6” wafer is typically 350 µm Nowadays up to 60% of the wafer – which is the largest part of the cost of a SiC chip – ends up removed by backgrinding Asuccessful splitting technology would mean being able to use the raw material two or more times and reducing device prices significantly The PCIM Europe 2024 – celebrating our success There are a lot of new device and package concepts to learn about at this year’s PCIM Europe conference as well as solutions to explore at the exhibition And there are many more current issues and problems to discuss The growing numbers attending PCIM Europe events shows the increasing engagement in our community In wider society while there is awareness of wind turbines and photovoltaic power there is little awareness of the vital supporting role that power electronics plays in enabling everything from LED lights to electric mobility and from renewable generation to the grid Even the AI hype would be unthinkable without power electronics for supplying the power to the servers The general public doesn’t yet know the importance and responsibility power electronics has in realising the potential of renewable energy and electrification in the fight against the upcoming climate disaster Prof Dr -Ing Thomas Basler is chairing the oral presentation session on IGBT on 12 June 2024 2 30 p m stage Brüssel 1 Im ag e Che m ni tz Uni ve rs ity o f Tec hn ol og y >BROXING< PCIM 2024 Stand 6-234 BROXING SA Via ai Campi 9 CH-6982 Lugano-Agno Switzerland Info@broxing com Tel + 41 91 922 0370 Fax +41 91 922 0371 H IG H C U R R EN T C O N TA C T EL EM EN TS fo r P C Ban d IM S A D V ER TI SE M EN T
