Dc/dc partial power converter based on pcb embedding technology

Abstract

Disclosed is a DC/DC partial power converter (PPC), comprising a plurality of first switching cells; a capacitive energy storage element; a plurality of second switching cells; and a printed circuit board (PCB). A power input terminal of the respective first switching cell is connectable to a respective DC power source. Power output terminals of the respective first switching cell and power input terminals of the respective second switching cell are connected in parallel to the capacitive energy storage element. A power output terminal of the respective second switching cell is connectable to a DC power output bus. The respective first or second switching cell comprises at least one die package being embedded in the PCB. Electrical terminals of the respective at least one embedded die package are connected with corresponding electrical terminals on the PCB. This improves a power density and cost of DC/DC partial power converters.
