  • Bidirectional power converters
    Patent number: 8593115
    Abstract: Circuits and methods for bidirectional power conversion are provided that allow mobile and other devices to generate power suitable to support multiple modes of operation. The bidirectional power converters of the present invention may operate in both step up and step down configurations rather than having a single dedicated conversion function and use many of the same components thereby reducing converter size and complexity.
    Type: Grant
    Filed: August 12, 2010
    Date of Patent: November 26, 2013
    Assignee: Linear Technology Corporation
    Inventors: William Walter, Sauparna Das
  • Bidirectional power converters
    Patent number: 8536840
    Abstract: Circuits and methods for bidirectional power conversion are provided that allow mobile and other devices to generate power suitable to support multiple modes of operation. The bidirectional power converters of the present invention may operate in both step up and step down configurations rather than having a single dedicated conversion function and use many of the same components thereby reducing converter size and complexity. In some embodiments, the converter of the present invention may be used to provide a power component of a communications link, such as a USB link.
