  • Motor drive with silicon carbide MOSFET switches
    Patent number: 10389263
    Abstract: Motor drive power conversion systems are provided including a rectifier and a switching inverter, wherein the switching devices of the rectifier, the inverter and/or of a DC/DC converter are silicon carbide switches, such as silicon carbide MOSFETs. Driver circuits are provided for providing bipolar gate drive signals to the silicon carbide MOSFETs, including providing negative gate-source voltage for controlling the off state of enhancement mode low side drivers and positive gate-source voltage for controlling the off state of enhancement mode high side drivers.
    Type: Grant
    Filed: October 2, 2017
    Date of Patent: August 20, 2019
    Assignee: Rockwell Automation Technologies, Inc.
    Inventors: Kevin Baumann, Richard Lukaszewski, Rangarajan Tallam, Lixiang Wei, Lee Gettelfinger, Garron Morris, Bruce Weiss, Neil Gollhardt, Navid R. Zargari, William Brumsickle, Robert Wright Reese, Stephen E. Denning
