  • System and method for removing energy from an electrical choke
    Patent number: 10746816
    Abstract: A system for removing energy from an electrical choke is provided. The system includes one or more cores, at least one inductive coupling, and a resistor. The one or more cores are configured to form part of the electrical choke by generating magnetic energy. The at least one inductive coupling is operative to convert the magnetic energy into electrical energy. The resistor is electrically connected to the at least one inductive coupling and operative to dissipate the electrical energy as heat.
    Type: Grant
    Filed: February 5, 2018
    Date of Patent: August 18, 2020
    Assignee: GENERAL ELECTRIC COMPANY
    Inventors: Douglas John Link, Scott Walterman, Randy Hladilek, Timothy Strait, Margaret Wiza, Melissa Freeman

  • System and method for supplying electrical power to a gradient amplifier
    Patent number: 10310038
    Abstract: A method for supplying electrical power to a gradient amplifier that drives a gradient coil for a magnetic resonance imaging system is provided. The method includes predicting a gradient voltage required to drive the gradient coil for a scan based at least in part on a gradient coil model. The method further includes calculating a voltage set point for a power supply based at least in part on the predicted gradient voltage. The method further includes providing electrical power to the gradient amplifier via the power supply based at least in part on the calculated voltage set point. The gradient coil model is based at least in part on historical data acquired prior to the scan.
