ROTATING TRANSFORMER AND INDUCTIVE COUPLING

Aspects of the present disclosure are generally directed to using a rotary transformer to transfer power for a wind turbine generator. Certain aspects of the present disclosure are directed to a multi-rotor wind turbine. The multi-rotor wind turbine generally includes a plurality of rotors, a plurality of electrical generators, each coupled to one of the plurality of rotors, and one or more rotary transformers configured to transfer power between the electrical generators and a power grid. In some aspects, each rotary transformer comprises a first winding coupled to one or more electrical generators of the plurality of electrical generators, and a second winding magnetically coupled to the first winding and coupled to the power grid, wherein the first winding is rotatable with respect to the second winding.
