Patents by Inventor Joel Mertes

Joel Mertes 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).

  • Drive output harmonic mitigation devices and methods of use thereof
    Patent number: 9571058
    Abstract: A filter for filtering a three-phase electrical power waveform produces a three-phase output power waveform. The filter has an inductor with three sets of first and second coils, each having a capacitor connected in series therewith. Each of the three sets of first and second coils has a tap intermediate the first and second coils where the output waveform is present, each tap capable of being connected to a load. In some embodiments, the inductor is passive adaptive and includes resistors for reducing current in-rush.
    Type: Grant
    Filed: June 30, 2015
    Date of Patent: February 14, 2017
    Assignee: MTE Corporation
    Inventors: Todd Shudarek, Joel Mertes
