Figure 1: PRM™ and VTM™ are the building blocks of FPA. PRMs are selected based on the system input voltage range and power requirements; VTMs are selected based on the output voltage range and current requirements. The PRM can be mounted anywhere in the system where convenient; the VTM should be mounted as close to the processor core as possible

Powering Clustered AI Processors
Paul Yeaman, Director of Application Engineering, Vicor Corporation

The recent introduction of new clustered AI ASIC processor based supercomputers are pushing the boundaries of power delivery networks to levels that were never imagined just a few years ago. With current levels approaching 100 kiloamps/ASIC cluster, innovation is needed across power system architectures, topologies, con
