Patents by Inventor Jonathan Robert Knight

Jonathan Robert Knight 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).

  • Publication number: 20110234157
    Abstract: A synchronous rectifier is arranged to rectify inductively coupled power using PETs (field effect transistors) to minimize the voltage drop of the rectifier, which minimizes power loss. Power loss is an important consideration in applications where fairly significant power is coupled to a device (such as a battery charger or other energy storage device) for a fairly short time (such as less than one hour) at a fairly low voltage (such as around 2.5 to 4.5 volts). Body diodes of the PETs can be used to supply power for bootstrapping and control logic for controlling the PFTs.
