A Multiphase Machine and Converter Topology for Renewable Energy Generation

This paper presents a new electrical machine and converter topology for renewable energy generation. The proposed topology lends itself well for direct integration into dc power delivery systems, featuring low speed generating units such as direct drive wind turbine generators. The machine and converter topology fully exploits the benefits of a multiphase system of the current-source type. The proposed topology allows both two-level and multi-level machine-converter configurations to cater for low and high voltage dc power systems.
