  • Maximum power point tracking device for a solar electric generation system and a tracking method for the same
    Patent number: 8805629
    Abstract: A maximum-power-point tracking device is provided for a solar electric-generation system that includes a solar battery and a DC/DC converter connected to the solar battery. The device includes a sampling module configured to detect output current and voltage values of the solar battery. A controlling module is configured to calculate a target current value according to the output current and voltage values and a preset current value, and output a controlling signal for controlling the value of a current according to the output current of the solar battery and the target current value. The device also includes a driving module configured to receive the controlling signal from the controlling module and output a driving signal to adjust a output current value of the DC/DC converter to close to the target current value and adjust an output power of the DC/DC converter.
