Rapid growth of artificial intelligence is forcing a rethink of data-centre power architectures. Legacy server designs were never intended to support the extreme power densities of modern AI workloads. These facilities are increasingly becoming what we might call “AI factories” where the primary goal is to optimize compute capability in a constrained physical footprint.
A key enabler for this transition is the use of 800 VDC distribution. The high voltage approach enables power scaling at the rack level from conventional levels to the megawatt range, which is essential for next generation accelerator platforms. 800 V direct power delivery to compute subsystems introduces new challenges in insulation coordination and device stress, but it also presents an opportunity to rethink how isolation is implemented. Here, Input-Series Output-Parallel (ISOP) converter topologies are becoming popular because of their modularity, scalability and efficiency.
