Direct 48-/1-V GaN-Based DC-DC Power Converter With Double Step-Down Architecture and Master-Slave AOT Control.

In modern power delivery systems, there has been an up-rising trend of migrating conventional two-stage dc-dc power conversion architecture to a single-stage one, in order to accomplish better efficiency and power density. In response to such a trend, this article presents a gallium nitride (GaN)-based power converter design that achieves direct 48-/1-V dc-dc power conversion with a single-stage d...
