The industry shift toward 800 VDC power distribution for AI server racks requires novel DC-DC converter architectures to optimize delivery. Because of its superior efficiency and power density, the Input-Series-Output-Parallel (ISOP) topology is rapidly becoming the standard. This paper analyzes three 800 V-input ISOP converters tailored for 50 V, 12 V, and 6 V nominal output rails. Implementing gallium nitride (GaN) transistors on both the primary and secondary switching sides enables these converters to establish new performance benchmarks for peak and full-load efficiency at each critical voltage node.
