  • Publication number: 20230083355
    Abstract: A system and method for compensating a faulty switch in a multi-level flying capacitor converter includes a converter capacitor arranged in parallel to an input, a first and second converter switches arranged respectively between first and second ends of the converter capacitor, first and second bypass switches respectively arranged in parallel to the first and second converter switches, wherein operation includes detecting a faulty converter level that includes at least one of the first and second converter switches, discharging all capacitors arranged in parallel to the input of the multi-level converter, wherein all capacitors comprise the converter capacitors and an input capacitor; closing the first and second bypass switches of the faulty converter level; adapting a modulation of the converter switches of the other converter levels; and restarting the multi-level converter.

  • Publication number: 20230060063
    Abstract: A modulator for a flying-capacitor type multilevel converter receives, at an input, a time-variant reference signal and provides, at an output, a sequence of target levels, to provide switching signals for switching between discrete output levels of the multilevel converter according to the shape of the reference signal. The modulator determines a critical level as an intermediate output level of the multilevel converter which is closest to the level of the reference signal; and outputs only target levels corresponding to output levels different from the critical level.

  • Publication number: 20060276518
    Abstract: This invention provides certain compounds, methods of their preparation, pharmaceutical compositions comprising the compounds, and their use in treating human or animal disorders. The compounds of the invention are useful as antagonists, or more preferably, partial antagonist of factor IX and thus, may be used to inhibit the intrinsic pathway of blood coagulation. The compounds are useful in a variety of applications including the management, treatment and/or control of diseases caused in part by the intrinsic clotting pathway utilizing factor IX. Such diseases or disease states include stroke, myocardial infarction, aneurysm surgery, and deep vein thrombosis associated with surgical procedures, long periods of confinement, and acquired or inherited pro-coagulant states.

  • Patent number: 4946359
    Abstract: The apparatus comprises a fixed cylindrical housing and a centrifugal disc closing the housing in the manner of a base, which disc is rigidly connected to a motor driven shaft. Above the centrifugal disc a ring is fitted into the housing. The distance of that ring from the centrifugal disc is such that material propelled outwards by the centrifugal disc and upwards at the wall of the housing is positively deflected at the lower curved surface of the ring.
