The benefits of supplying the rotor circuit of a Doubly Fed Induction Generator (DFIG) by the
Modular Multilevel Matrix Converter (M3C) are presented. The M3C allows higher rotor voltages,
lower rotor currents and a higher redundancy compared to existing solutions. Filters
are dispensable due to the generated multilevel voltages. In case of a line voltage drop the
M3C arm voltages can be used to generate temporarily higher rotor voltages which may help
to control the rotor currents during faults.
