Patents by Inventor Andrew David McArthur

Andrew David McArthur 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).

  • System and method for reducing partial discharge in high voltage planar transformers
    Patent number: 10236113
    Abstract: A device includes a printed circuit board (PCB). The device may also include a high voltage coil disposed on the PCB and a low voltage coil disposed on the PCB. Further, a conductive shield forms a three-dimensional enclosure around the high voltage coil and confines an electric field generated by the device to the PCB.
    Type: Grant

    Date of Patent: March 19, 2019
    Assignee: General Electric Company

  • Online frequency response characterization system and method
    Patent number: 9798318
    Abstract: A system may include a controller that may control operations of a device according to a control loop and characterize a frequency response of the device while the device is operating. The controller may characterize the frequency response by adding a perturbation signal to any signal in the control loop. The controller may then determine a first transformed signal by performing a first discrete Fourier transform on a first signal in the control loop at a frequency of the perturbation signal and determine a second transformed signal by performing a second discrete Fourier transform on a second signal in the control loop at the frequency of the perturbation signal. The controller may then determine the frequency response at the frequency by comparing a first amplitude and a first phase of the first transformed signal to a second amplitude and a second phase of the second transformed signal.
