Technology & Market Analyst, Power Electronics & Battery
Yole Group
Hassan contributes on a day-to-day basis to the analysis of power converter topology trending in all power segments (rails, xEV, wind, datacom, PV…).
Previously, Hassan has worked in the R&D department at ‘Eaton e-Mobility’. He has established a deep technical root-cause analysis for the issues coming from the production line of a DC/DC converter. He contributed to the design of the next generation of the power converter.
Before, Hassan has developed an aeronautic prototype dealing with the green taxiing. He was the responsible of electrical storage system design as well as the EMC filter. He has expertise in UPS, battery storage system and PV installation.
Hassan obtained a PhD in EMC in 2017 from École Centrale de Lyon (France), where he developed electrical models for equipment seeking the acceleration of qualification of aircraft equipment.
Hassan earned a bachelor’s degree from the Lebanese faculty of engineering (Lebanon).

Data Center Power Train: Emerging Solutions for Uncertain Market!
AI-driven data centers are reshaping the entire power train, from solid-state transformers (SST) and front-end PSUs to high-voltage IBCs, board-level IBCs, and POLs delivering several hundreds of amperes to processors. Architectures are moving toward higher distribution voltages, stronger integration, and vertical power delivery. However, as of 2026, many of the required products across this chain simply do not exist. Power semiconductors, packaging, protection, and magnetics are being pushed beyond their original design limits. Some technologies must be adapted, while others will need to be newly developed to meet emerging requirements in current density, efficiency, reliability, and footprint. At the same time, parts of the ecosystem remain cautious about the mid-term sustainability of AI investments, expecting a potential market slowdown. This presentation discusses how these technology gaps and market uncertainties interact across the data center power train, and what this tension means for power electronics roadmaps and innovation strategies.
