The 48V-1V Low-Profile Direct Power Converter, described in this article, is a high-current single-stage converter for high-performance applications. Based on the Direct Power Converter (DPx), this power converter present steps forwards by increasing the gain in four and reducing the height from 14 mm to 5 mm. Regarding the magnetic structure, the Segmented Winding Transformer was replaced by a Planar Matrix Transformer with commercial magnetic cores. Due to the height issue, this low-profile converter becomes a so-called electric center, worsening the conversion performance but improving the manufacturability. A prototype was tested up to 350A with 412W/in3, reaching a peak efficiency of 94% at 70A and a full load efficiency of 85%.
