Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
The best methods for distributing high currents while minimizing resistive and inductive losses.
Strategies to deal with multiple outputs and power levels in nontraditional board spaces.
Hosted by David Berry, Senior Principal Applications Engineer at Vicor Corporation, this series helps engineers solve complex, high-performance power distribution challenges. Across these sessions, you will learn to navigate the architectural transition from 12V to high-efficiency 48V systems and optimize bus regulation. The series provides practical design strategies to mitigate severe distribution losses, master transient responses, and fit high-power rails into non-traditional board spaces. Ultimately, these videos deliver the exact methodologies needed to maximize power density without expanding your board footprint.
