  • Publication number: 20260040978
    Abstract: A modular POL component can be arranged to define a half-bridge converter topology, and can be coupled with other modular POL power components to define a full-bridge or 3-phase AC converter topology based on a desired power output. The assembled POL components can be mounted on a common electrically insulative substrate to define a POL power conversion device to provide the desired power output.

  • Publication number: 20250300435
    Abstract: A power overlay module assembly that provides for or meets a desired power demand. The power overlay module assembly comprises power overlay tiles, a base, a direct current (DC) input bus bar, and an alternating current (AC) bus bar. The power overlay tiles have an arrangement of power switching components. The base receives the power overlay tiles. The DC input bus bar is electrically coupled to the power overlay tiles. The AC output bus bar comprises a non-conductive surface layer. The non-conductive surface layer insulates the AC output bus bar from the DC input bus bar, and the AC output bus bar is electrically coupled to the power overlay tiles.
