The present invention detects current feedback signals i a and i b and grid phase voltage input signals U a_g , U b_g , and U c_g for controlling and synchronizing the three-phase output voltages U a_p , U b_p , U c_p , of the supplemental power supply (10) with the power grid. The method (100) of the present invention detects the three-phase voltages of both the supplemental power supply, U a_p , U b_p , U c_p and the power grid U a_g , U b_g , U c_g , and converts the detected voltages into components U d_com , U q_com on a d-q plane.",
