  • Patent number: 12283878
    Abstract: A method for operating a power electronic converter comprising at least one power semiconductor device is provided. The method comprises the determination of the at least one current limit, by carrying out a first operation if the temperature of the at least one semiconductor device is above an upper temperature threshold in order to decrease the current limit, and by carrying out a second operation if the temperature of the at least one semiconductor device is below a lower temperature threshold in order to increase the current limit.
    Type: Grant

  • Patent number: 10855199
    Abstract: A method of discharging a Modular Multilevel Converter (MMC) includes a plurality of phase legs connected in delta configuration. Each leg includes a plurality of series connected submodules, each submodule including an energy storage. The method includes disconnecting the MMC from an electrical grid, discharging the energy storages by means of a circulating current, and reconnecting the MMC to the electrical grid. The discharging includes, for each phase leg, setting a voltage reference, and sequentially selecting submodules in zero state by means of a sorting algorithm for switching each of the selected submodules to plus or minus state until the voltage deviation from the set voltage reference of the energy storage of each submodule in the phase leg is within a predefined range.

  • Patent number: 8980299
    Abstract: A method of making a biocompatible, implantable medical device, including a vascular closure device is disclosed. The method includes forming a biocompatible polymer into at least one fiber and randomly orienting the at least one fiber into a fibrous structure having at least one interstitial spaces. Polymeric materials may be utilized to fabricate any of these devices. The polymeric materials may include additives such as drugs or other bioactive agents as well as antibacterial agents. In such instances, at least one agent, in therapeutic dosage, is incorporated into at least one of the fibrous structure and the at least one fiber.

  • Publication number: 20060091034
    Abstract: A method for making an antimicrobial suture comprising the steps of positioning an antimicrobial agent source within a package comprising an inner surface, said antimicrobial agent being selected from the group consisting of halogenated hydroxyl ethers, acyloxydiphenyl ethers, and combinations thereof; positioning a medical device within the package; and subjecting the package, the antimicrobial agent source and the medical device to time, temperature and pressure conditions sufficient to vapor transfer an effective amount of the antimicrobial agent from the antimicrobial agent source to the medical device, thereby substantially inhibiting bacterial colonization on the medical device.

  • Publication number: 20060091035
    Abstract: A method of making a packaged antimicrobial suture comprising the steps of providing a containment compartment that is substantially free of an antimicrobial agent; positioning a suture within the containment compartment, said suture comprising one or more surfaces having an antimicrobial agent disposed thereon, said antimicrobial agent being selected from the group consisting of halogenated hydroxyl ethers, acyloxydiphenyl ethers, and combinations thereof; placing the containment compartment having the suture in an outer package; and subjecting the outer package, the containment compartment and the suture to time, temperature and pressure conditions sufficient to vapor transfer an effective amount of the antimicrobial agent from the suture to the containment compartment, while retaining an effective amount of said antimicrobial agent on the suture, thereby substantially inhibiting bacterial colonization on the suture and the containment compartment.
