  • Distributed power system, DC-DC converter, and power conditioner
    Patent number: 9966866
    Abstract: A distributed power system that is connected to a utility grid during both daytime and nighttime includes a plurality of power supplies including a solar array, a non-isolated DC-DC converter that has an input terminal and an output terminal and raises, at a predetermined step-up ratio, a DC voltage input from the power supplies via the input terminal and outputs the DC voltage via the output terminal, an inverter that converts the DC voltage output from the DC-DC converter via the output terminal into an alternating current, and a potential adjustment section that adjusts a potential at a negative electrode of the solar array to a potential higher than a potential at a negative electrode of the inverter at least during nighttime.
    Type: Grant
    Filed: August 21, 2017
    Date of Patent: May 8, 2018
    Assignee: OMRON Corporation
    Inventors: Yasuhiro Tsubota, Tomoya Irie, Kunio Aono, Takao Mizokami, Masao Mabuchi, Kenji Kobayashi
