1. A method of controlling a hybrid power convertor, comprising:

  • providing a voltage to make the hybrid power convertor generate an output voltage;

    determining a rated voltage based on the output voltage; and

    performing an initial voltage determining step, comprising;

    when the voltage is greater than the output voltage, entering a buck mode; and

    when the voltage is not greater than the output voltage, entering a boost mode,wherein the buck mode alternatively performs a switching conversion mode or a linear regulation mode, and the boost mode alternatively performs a linear-like regulation mode or a boost conversion mode.
