Abstract:
    A tracking and control method for the hybridded maximum power point of the photovoltaic pumping system. It contains: a, the check and choice logo, it will turn to the step b if it is ture, or it will turn to the step d. b, the output frequency of the inverter will be adjusted the running of the multiple criteria. C, the choice logo will become untrue and the reference voltage Verf=V (n), and the real running time of the normal voltage method, tCV, will be reset, and turn to the step a, or turn to the step a. d, the output frequency of the inverter will be adjusted by the running of the normal voltage method. e, To add a control cycle into the running time of the normal voltage method, tvc, the choice logo will be true if the tvc
