Abstract: Multiphase generator-conversion systems are disclosed. The system includes a multiphase generator having one rotor and m+1 number of electromagnetically coupled stators, each stator having a plurality of phase legs. The system includes a converter having m+1 conversion lines, each conversion line connected to the plurality of phase legs of one of the m+1 stators. Each conversion line has a rectification module. At most m of the m+1 rectification modules has an active filtering converter. At least one of the m+1 rectification modules has a passive rectifier. At least one of the active filtering converters is configured to directly control its current to vary the magnetic flux of the stator to which it is connected and indirectly affect the magnetic flux of the rest of the stators through the electromagnetic coupling. Also disclosed are wind turbines that include generation conversion systems and methods of mitigating harmonics in multi-phase generator-conversion systems.
