Abstract
In the field of power converters for data centers,
the two-stage architecture has received widespread attentions
due to its various advantages. Especially, the switched-capacitor
voltage regulator (SCVR) becomes popular as the second-stage
converter owing to its high efficiency and power density. However,
the SCVR su ffers from poor voltage regulation and limited load
capacity. To address these limitations, this article presents a two-
stage converter featuring a regulated resonant switched-capacito
