Artificial intelligence workloads are rapidly reshaping data center power architectures. Conventional server infrastructure was not originally designed to sustain today’s extreme compute density requirements. As a result, modern facilities increasingly resemble “AI factories,” where maximizing computational throughput per rack is a primary objective.

The move to 800 VDC distribution is one of the main things that makes this change possible. This lets rack power grow from hundreds of kilowatts to megawatt-class levels, which are needed by next-generation AI platforms. In this architecture, the 800 V rail directly powers the compute trays. This creates new problems with insulation and device ratings, but it also gives us a chance to redesign the isolation stage. Input-Series Output-Parallel (ISOP) converter topologies are becoming strong candidates for this job because they are scalable and efficient.
