Phase Shift Regulated Resonant Switched-Capacitor-Based Intermediate Bus Converter for 48 V Data Center Power System

IEEE transactions on industrial electronics (1982. Print)
In the two-stage architecture of 48 V data center power systems, the front-end intermediate bus converter (IBC) needs to adapt to both 48 V nominal input voltage and a wide input voltage range of the backup battery (typically 40 V–60 V).
