  • Patent number: 9310822
    Abstract: Disclosed is a solar photovoltaic power generator system that includes a solar cell panel and a power conditioner that controls a voltage or a current of generated power output from the solar cell panel as an operating value in accordance with a characteristic of the solar cell panel to search a maximum output point of the generated power so as to be supplied to a power system. The power conditioner includes a data memory module that stores a plurality of operating values and a plurality of patterns of the generated powers from the solar cell panel based on the operating values, and a maximum power point tracking module that adds a new operating value based on the pattern of the generated power in the past to calculate the operating values for the next search, and sets the maximum value through an algorithm.
    Type: Grant

  • Patent number: 4502112
    Abstract: In a sequence control apparatus using a microprocessor performing its processing of operation in terms of one word as the unit therefor, a change indicating signal from a process condition detecting or measuring instrument connected to an I/O unit is taken into the microprocessor in a form combined with predetermined pattern data. With the resulting composite data, the contents of those bits of an accumulator in the microprocessor which do not correspond to the change indicating signal can be optionally processed.
