Abstract—This paper presents a power supply using an in-creased switching frequency to minimize the size of energy storing components, thereby addressing the demands for increased power densities in power supplies. This document introduces a new, complete power supply unit (PSU) for AI data centers and servers. Intended audience The document is intended for R&D engineers, hardware designers, and developers of power electronic systems. In SMPS, the series element, RS, is replaced by a semiconductor switch, which offers very low resistance at the ON state (minimizing conduction loss), and very high resistance at the OFF state (blocking the conduction). A switching power supply (often abbreviated SMPS for switched-mode power supply) is an electronic power converter known for efficiently transforming AC power into stable DC voltage through rapid switching techniques. These power supplies are widely used in a variety of applications, such as telecommunications, computing, automotive.
