The increasing power demands of AI and compute are driving a shift towards higher voltage DC architectures. European alliances are collaborating on open standards to boost efficiency by reducing conversion steps. This approach aims to overcome rack-level constraints by rethinking power delivery at 800 volts.
Delta Electronics' Kelly Gray explains how AI infrastructure is driving a convergence in AI data center design, encompassing high-voltage DC power, liquid cooling, microgrids, digital twins, and chip-to-grid systems to build the next generation of AI factories.
