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
Increase throughput by delivering more power to more cells faster
High density and efficiency
Bidirectional capability
Faster time to market
Wide input range
Optimized DC-DC power conversion to meet new market demands
Efficient and power-dense
Using a modular approach to power, Vicor high performance power modules require dramatically less space than traditional discrete power solutions while providing high efficiency and power density. This enables increased battery throughput without increasing floor space.
Advanced power architectures
Vicor patented power architectures and topologies enable power designs for all phases of the battery lifecycle that maximize the efficiency of systems by utilizing fixed-ratio converters and easily modifying available power levels by power matching and paralleling modules.
Power flow in both directions to recycle energy
Vicor bidirectional power modules allow electricity to flow in two directions, making recycling energy used in the battery charging process effortless and efficient. The recycled energy can be used to charge different cells, for other manufacturing processes, or sent back into the grid for further cost savings.
Quickly implement a power solution
Vicor provides tested and qualified power modules to build power delivery networks that can be designed quickly without all the wasted time and effort to test and certify a new discrete design. This enables our customers to get to market faster, giving them a distinct advantage over their competition.
The power delivery network
Isolated, high-density BCM fixed-ratio converters safely and reliably convert a high voltage (up to 800V) input into standard safety extra low voltage (SELV) bus output voltages of either 12, 24 or 48V for design flexibility. The voltage can then be regulated down to the level appropriate for battery cell formation, 4.2V in this example. The BCM modules are power matched and paralleled to deliver more power and provide for bidirectional power flow, allowing the system to reclaim the energy used in the battery cell formation process by sending it back into the grid or to an energy storage device where it can be reused to power additional battery cells in the future.
