Abstract
A method for coupling an inverter to an alternating voltage source, the inverter comprising a current controller, which controls phase currents and implements reference current. The method comprises steps of giving zero current as the reference current for the current controller, determining phase voltages of the inverter, determining frequency of the alternating voltage source from the determined phase voltages, and synchronizing and coupling the inverter to the determined frequency of the alternating voltage source.
