  • Unmanned aerial vehicle off-site landing system
    Patent number: 11250713
    Abstract: A fixed wing unmanned aircraft and a method for operating the same are provided.
    Type: Grant
    Filed: March 27, 2019
    Date of Patent: February 15, 2022
    Assignee: HONEYWELL INTERNATIONAL INC.
    Inventors: Yang Liu, Alan Bruce Hickman, Xiaodong Chen, Shuai Chen, Wenwan Feng, Lei Zhang, Yunfei Zou
  • Current-voltage curve scan method for photovoltaic module, and optimizer
    Patent number: 11031906
    Abstract: An IV curve scan method for a photovoltaic module and an optimizer are provided. The optimizer receives an IV curve scan signal and controls an output voltage of the photovoltaic module corresponding to the IV curve scan signal to change from an open-circuit voltage to a preset minimum voltage according to a preset rule, while photovoltaic module connected to another optimizer can still operate normally, so that the system can operate normally. Then the optimizer uploads IV curve data of the photovoltaic module corresponding to the IV curve scan signal, to complete an IV curve scan on a single photovoltaic module.

  • Photovoltaic rapid shutdown device and photovoltaic system
    Patent number: 10075127
    Abstract: A photovoltaic rapid shutdown device and a photovoltaic system are provided. The device includes a first switch, a second switch, a bypass diode, an auxiliary power supply, a control circuit and a communication circuit. One of multiple photovoltaic modules serves as a power supplying photovoltaic module, and an output terminal of the power supplying photovoltaic module is connected to an input terminal of the auxiliary power supply. The first switch is connected in series between the power supplying photovoltaic module and an adjacent photovoltaic module. Two terminals of the second switch are connected to positive and negative output terminals of a branch formed by the multiple photovoltaic modules connected in series, respectively. A cathode of the bypass diode is connected to a low voltage terminal of the adjacent photovoltaic module.
