Abstract
The present invention provides a high efficiency, high density GaN-based power converter comprising: a transformer; a magnetic coupler; a primary switch; a secondary switch; a primary controller; a secondary controller; a multi-layered print circuit board (PCB) comprising: one or more planar coils respectively formed on one or more PCB layers and aligned with each other for constructing the transformer and the coupler; and a plurality of conducting traces and vias for providing electrical connection among the transformer, the coupler, a primary switch, a secondary switch, a primary controller and a secondary controller. The power converter further comprises a pair of ferrite cores being fixed to a top surface and a bottom surface of the PCB respectively and commonly shared by the transformer and the coupler.
