Benefits of Operating Doubly Fed Induction Generators by Modular Multilevel Matrix Converters

, 2013
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.
