Power Supply Unit for GPU and CPU Boards

A power supply unit (PSU) for data centers delivers power to individual graphics processing unit (GPU)/CPU boards by converting high-voltage DC (typically 400 V/800 V) to lower-voltage DC (typically 96 V/48 V). Additional conversion stages aretipically used to supply power to individual components (down to 3 V). Delivering a highly efficient conversion process, the PSU supports the power demands of thousands of boards in a data center while its high-speed switching capability reduces the cost of expensive passive components such as inductors or capacitors.
