AI platforms have driven server power supply output well beyond the 3.3 kW to 5.5 kW levels that were once considered high-end, with rack power densities continuing to climb as GPU and ASIC compute density increases. These demands put greater pressure on secondary rectifier size, component count, and cost. At a fixed output voltage, higher power requires proportionally higher current, making MOSFET selection and rectifier topology closely linked design decisions.
