Patent number: 10361629Abstract: An improved power manager includes a power bus (410) and multiple device ports (1-5), with at least one device port configured as a universal port (3 and 4) to be selectively connected to the power bus over an input power channel that includes an input power converter (510) or over a output or universal power channel (412, 416) that includes an output power converter (440, 442). The universal power channel (412) allows the input port (4) to be selected as an output power channel instead of an input power channel (i.e. operated as a universal port) for outputting power to device port (4) over power converter (440). The improved power manager (500) includes operating modes for altering an operating voltage of the power bus (505), to minimize overall power conversion losses due to DC to DC power conversions used to connect non-bus voltage compatible power devices to the power bus.Type: GrantFiled: April 4, 2017Date of Patent: July 23, 2019Assignee: Revision Military Ltd.Inventors: David N. Long, Seth M. Dziengeleski, James D. Kazmierczak, Benjamin Apollonio, Michael J. Grennan, My H. Lac

Patent number: 5565837Abstract: In a low-profile printed circuit device, a first substrate is provided with a planar magnetic transformer and a planar magnetic inductor. The transformer and the inductor each have a primary winding defining spiral conductive patterns disposed on opposite sides of the first substrate relative to each other, and an inductive core extending through a respective inner aperture formed through the first substrate and surrounded by the respective primary winding. A second substrate is also provided, having a secondary transformer winding and a secondary inductor winding. Each secondary winding defines respective spiral conductive patterns disposed on opposite sides of the second substrate, and surrounding respective inner apertures extending through the second substrate.Type: GrantFiled: June 13, 1994Date of Patent: October 15, 1996Assignee: Nidec America CorporationInventors: Paul W. Godek, Michael J. Grennan

Patent number: 5321380Abstract: The present invention provides a low-profile printed circuit board including a substrate having at least one planar magnetic element supported thereon. The element includes a planar winding integral with the conductive circuit formed on either one or the other side of the board, and electrical communication is made from one side of the board to the other side via plated through holes provided in the substrate. Additional planar windings may be surface mounted to the winding carried by the substrate. A dielectric coating is also provided which completely isolates the winding of the planar magnetic element.Type: GrantFiled: November 6, 1992Date of Patent: June 14, 1994Assignee: Power General CorporationInventors: Paul W.
