  • Electrostatic motor having unipolar drive
    Patent number: 11362600
    Abstract: A generator/controller for electrostatic motors exploits properties of a delta-connected electrostatic motor to accommodate high common mode DC offset voltages thus permitting construction of an electrostatic drive circuit outputting unipolar sinusoidal power and having a substantial reduction in the complexity and size.
    Type: Grant
    Filed: March 6, 2020
    Date of Patent: June 14, 2022
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Peter Killeen, Daniel Colin Ludois

  • Sensorless controller for electrostatic machine
    Patent number: 11012003
    Abstract: A variable speed drive for an electrostatic motor provides feedback control according to rotor position and/or rotor rotational rate deduced from back currents (back-MMF). Extraction of the back currents is performed by a modeling of the stator and the development of isolated stator voltages from plate voltage measurements.

  • Low profile, highly configurable, current sharing paralleled wide band gap power device power module
    Patent number: 10136529
    Abstract: A method of making a power module includes providing a base plate defining a topology pattern, providing a power substrate above the base plate, providing at least two power contacts and arranging solder catches in the at least two power contacts, soldering the at least two power contacts to the power substrate utilizing the solder catches, and securing a housing to the power substrate.
