A flying capacitor multilevel dual-active bridge converter for interfacing high voltage in more-electric aircraft
… must increase, placing new demands on the power converters interfacing high-voltage buses with low-voltage buses and storage. While the dual-active bridge (DAB) converter has traditionally served this role, its reliance on single high-voltage devices constrains achievable switching frequency, …

Power Interface Design and System Stability Analysis for 400 V DC-Powered Data Centers
… cost in data centers. A cascaded totem-pole bridgeless PFC converter to convert grid ac voltage to the 400 V dc voltage is proposed in this work. Three main control strategies are developed for the power converters. First, a model predictive control is developed for the cascaded totem-pole …

A series-stacked power delivery architecture with isolated converters for energy efficient data centers
… 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 the DC bus voltage to a lower voltage, which is typically …
