1. and from a net inverse method, it is characterized in that, comprising:

  • The direct current of the photovoltaic array input that S10, reception connect in advance;

    S20, judge whether described galvanic input voltage signal is greater than predetermined threshold value;

    If be greater than, perform S30;

    S30, activate and be in the default three phase full bridge IGBT inverter circuit of park mode, and by described three phase full bridge IGBT inverter circuit, described direct current is carried out three phase full bridge IGBT inversion, obtain the three-phase alternating current of high frequency;

    S40, the three-phase alternating current of described high frequency is carried out isolation boosting after export.
