  • Publication number: 20200144956
    Abstract: In one embodiment, a photovoltaic system includes a photovoltaic array, an energy storage converter, a storage battery, and a photovoltaic inverter. The energy storage is configured to: when electrical energy of a direct current generated by the photovoltaic array is greater than electrical energy required by a power grid in a unit time, supply one portion of the input direct current to the photovoltaic inverter, and store the other portion of the direct current into the storage battery; or when electrical energy of a direct current generated by the photovoltaic array is less than electrical energy required by a power grid in a unit time, supply the input direct current to the photovoltaic inverter as one portion of a direct current, and obtain the other portion of the direct current from the storage battery and supply the other portion of the direct current to the photovoltaic inverter.

  • Patent number: 8658972
    Abstract: An ion mobility tube comprises an ionization source chamber having a center ionization source chamber hole, an ion door, a mobility region unit having a center mobility tube chamber, a constraining grid, and a Faraday disk, and the ionization source chamber, the ion door, the mobility region unit, the constraining grid, and the Faraday disk are laminated together in sequence in a front-rear direction, wherein the mobility region unit comprises a first insulator and first metal electrode sheets concentrically fixed to a front surface and a back surface of the first insulator respectively. The mobility region unit comprises the first insulator and the first metal electrode sheets which are integral. Therefore, the ion mobility tube is advantageous in simplified manufacturing, and convenient for detachment and assembly.
