  • Compensation for variable voltage
    Patent number: 6586904
    Abstract: A switched reluctance drive is supplied from a voltage source which varies from the voltage at which the control laws for the drive were determined. The control system compensates for this by modifying both the speed and torque values used to determine the correct firing angles for the demanded load. The system works over a very wide range of voltage variation and is independent of the shape of the torque/speed curve of the drive.
    Type: Grant

    Date of Patent: July 1, 2003
    Assignee: Switched Reluctance Drives, Ltd.
