  • Bus bar with integrated voltage rise time filter
    Patent number: 10381897
    Abstract: A bus bar or similar high current conductor may be sheathed in a high relative permeability material formed in layers to both increase the inductance of that conductor and to provide a capacitance and resistance useful for forming a low pass filter to reduce the rise time of the voltage signals on the bus bar such as can be damaging to motor insulation and the like.
    Type: Grant
    Filed: July 25, 2017
    Date of Patent: August 13, 2019
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Daniel Colin Ludois, Andy Lee Schroedermeier

  • Integrated capacitor and inductor with low parasitic inductance
    Patent number: 9934903
    Abstract: A combination capacitor and inductor employ a common volume of high permeability material for energy-storing electrical and magnetic fields thereby reducing the bulk of these components with respect to separate components of comparable value. Capacitor conductors are arranged so that while proximate to the high permeability material they provide countervailing current flows to minimize parasitic inductance exacerbated by the high permeability material.
