Application examples
High performance computing
The Vicor NBM and DCM give data centers the flexibility to power legacy 12V boards when migrating to a 48V data center infrastructure. Utilizing the bidirectionality of the NBM allows for integrating the latest GPU into a legacy 12V infrastructure.
Automotive
The Vicor DCM and NBM enable the automobile industry to innovate with efficient 48V architectures while eliminating the gating factors of risk and timeframes reengineering the many legacy 12V systems being used in xEVs.
Battery testing
The Vicor DCM allows for an easier and quicker transition to a 48V architecture by providing conversion for legacy 12V buses powering the downstream cell monitor/balancing control units, delivering significant size, weight, and efficiency benefits.
