📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、EV・パワーエレクトロニクス分野の省エネ・高効率化技術として位置づけられる。SiC/GaN実装は国内自動車・電機メーカーの競争力やサプライチェーン強靱化に直結するが、SSBJや有報などの開示要件との直接的な接続は弱い。
In the global GX context
Globally, this sits in the hardware layer of the energy transition — improving converter efficiency and power density underpins EV and grid electrification. It is largely a technical engineering contribution rather than disclosure scholarship, so its relevance to TCFD/ISSB/CSRD reporting frameworks is indirect.

📄 Abstract（原文）
In order to succeed in the energy transition, static converters must address several issues such as improving efficiency, reducing electromagnetic interference and increasing power density. Concerning this last point, the solution implemented today is the use of large gap components (SiC and GaN) because they switch faster than their silicon counterparts and therefore allow to reduce losses (decrease of the volume of the heatsink) and/or increase the switching frequency (decrease of the volume of passive components). In this context, this thesis aims to evaluate a complementary technological proposal to improve the compactness of the converters by optimizing the volume of the cooling system. The basic idea is to optimize the distribution of the heat sources (chips) in the heatsink volume while considerably reducing the number of thermal interfaces through a modular 3D packaging with low parasitic inductance adapted to fast vertical components.Several types of elementary switching cells have been designed and realized using different 3D assembly technologies. The characterization means and methods were adapted to the architecture of these cells, and experimental measurements allowed to evaluate the electrical and thermal performances achievable with this technology. Electromagnetic simulations have then confirmed the results of parasitic inductance measurements, and allowed the detailed analysis of the switching cell in order to give first design rules. Finally, the interactions between switching cells were studied by electromagnetic simulations and thermal measurements in order to determine (by simulations) the volumetric and mass power density that could be reached in the case of a three-phase 48V-12 kW inverter for hybrid vehicles. A demonstrator has been designed and tested. ; Pour réussir la transition énergétique, les convertisseurs statiques doivent répondre à plusieurs problématiques comme l’amélioration du rendement, la réduction des perturbations électromagnétiques ou l’augmentation de la densité de ...
