Disclosed is an automatic synchronous parallelization apparatus capable of suppressing an inrush current by automatically adjusting the magnitude, the frequency, and the phase of the voltage when a single-phase voltage-type DC-to-AC converting device perfo...

The method for synchronising an electric machine (1) with an electric grid (2) comprises the steps of synchronising the frequency of the generator (1) with that of the grid (2) and regulating the voltage of the generator (1) towards the voltage of the grid...
