Power electronics stands at the crossroad of highly convoluted disciplines of physics: thermal science, mechanics and electronics. In order to respond to the growing and demanding automotive market, designers have no choice but to assemble off-the-shelf parts, keeping the onus of managing themselves thermal losses and stray inductances at interfaces. Power mechatronics is the buzz word for this. It has for long envisioned double-sided cooling and wire-bondless interconnections as ways to go. Merging those impediments and opportunities into a global solution, aPSI3D has developed an integrated approach for multi-physical co-design with its customers, offering both plug-in cooled power modules and maximum value transfer to the inverter. Eventually, a 50% power module with imbedded cold plate size reduction for a 100kW inverter is obtained vs. state-of-the art pin fin standard products.
With a 10nH stray inductance, this solution is paving the way to more than 100A wide bandgap semiconductor die based highly efficient power modules.

INGENIEURS DE L'AUTO SE DIGITALISE

 

 

La revue Ingénieurs de l’Auto est maintenant diffusée en print et on line. Une grande première pour la SIA avec ce numéro 865, disponible au format numérique.

Cette version digitale sera, à chaque numéro, réservée aux membres de la SIA abonnés.

Exceptionnellement pour ce premier numéro on line, et en lien avec la situation de confinement et de télétravail de beaucoup d’ingénieurs de notre industrie, la version digitale du numéro de Mai est accessible à tous.
