A series-stacked power delivery architecture with isolated converters for energy efficient data centers
… The conventional way of delivering DC power to a server rack in data centers generally contains a central converter that regulates a DC bus, which is typically at 380V rectified grid voltage. This 380V bus voltage is in turn fed to each server rack and one DC-DC converter per server then converts …
