Patents by Inventor John P. Deyst

John P. Deyst has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Switching system
    Patent number: 6643149
    Abstract: A voltage source inverter generating a poly phase AC signal is provided that includes an SVPWM controller. The controller is adapted to modify the switching pattern at low sine-wave frequencies creating a more even distribution of the conduction losses. The switching pattern periodically changes the sequence (or rotational sense) of the space vector components from clock-wise to counter-clock-wise direction, and vice-versa.
    Type: Grant
    Filed: October 15, 2001
    Date of Patent: November 4, 2003
    Assignee: Solectria Corporation
