Claim Text:
1. A method for feeding an unbalanced, three-phase current into a three-phase AC voltage system, the method comprising: using at least one first DC connection to provide a first electrical signal to at least one first inverter module, using at least one second DC connection to provide a second electrical signal to at least one second inverter module, using the at least one first inverter module to generate a positive phase-sequence system having a first set of components for the current to be fed in, using the at least one second inverter module to generate a negative phase-sequence system having a second set of components for the current to be fed in, the second set of components being offset from the first set of components, superimposing the positive phase-sequence system and the negative phase-sequence system to form a superimposed unbalanced, three-phase current to be fed in, and feeding the superimposed unbalanced, three-phase current into the three-phase AC voltage system.
