The 48V-1V Low-Profile Direct Power Converter, described in this paper, is a single-stage converter for high-current applications with height limitation. Based on the DPx converter, this 5mm-height power converter takes steps forwards by using standard PCB and a Planar Matrix Transformer with commercial cores. This Low-Profile converter becomes a so-called electric center, worsening the conversion performance but improving the manufacturability. A non-optimized prototype was built and tested up…

With the proposed current-cancellation-based heterogeneous integration method, most of the high-current printed circuit board (PCB) windings of the transformer are replaced by power switches and capacitors, and almost zero PCB winding is achieved for the high-current secondary windings of the DCX.
