    摘要: The present invention proposes a circuit for converting DC into AC pulsed voltage. The circuit comprises two or four controllable semiconductor switches as well as a corresponding controller unit. The controller unit controls the opening and closing of the two or four controllable semiconductor switches using a preset control mode. When the circuit is used as the driver circuit of a capacitive load such as a DBD lamp, the luminous efficiency of the DBD lamp is improved.

    摘要: Power conversion apparatus and methods are presented for providing electrical power to a grid or other load in which a synchronous machine is driven by a wind turbine or other prime mover to provide generator power to a switching type current source converter (CSC), with a current source rectifier (CSR) of the CSC being switched to provide d-axis control of the synchronous machine current based on grid power factor feedback, and with a current source inverter (CSI) of the CSC being switched to provide leading firing angle control and selective employment of dumping resists to dissipate excess generator energy in a fault mode when a grid voltage drops below a predetermined level.

    摘要: There is provided herein cross-linked, phosphorescent micro- and nanoparticles and applications of those particles. The invention uses halogen-containing polymers and co-polymers (HCPs) as an encapsulation matrix for organic and organometallic phosphorescent compounds to form micro- or nanoparticles. The phosphorescence of these encapsulated phosphorescent particles is substantially unaffected by phosphorescence quenchers such as oxygen and water molecules at ambient conditions. The invention provides methods of making cross-linked phosphorescent particles. HCPs may be directly cross-linked through linking moieties that are a part of the polymer, or cross-linked through other separate bridging or cross-linking materials Cross-linked particles are more stable than the non-cross-linked counterparts and more resistant to temperature, surfactants, and organic solvents.

    摘要: The invention involves encapsulation of phosphorescent molecules in polymeric matrices to prevent phosphorescence quenching. Specifically, polymers containing a significant portion of halogens have been found to be good matrices for encapsulation of phosphorescent molecules to provide strong phosphorescence at ambient conditions. Those encapsulated phosphorescent molecules can find a wide variety of applications for detection of many species, including biological and chemical molecules as well as micro-organisms.
