    Abstract: An energy generation system includes a turbine, an electric generator, a step-up transformer, and a converter. The turbine is operable to extract energy from a fluid flow and convert the extracted energy into mechanical energy. The electric generator is operable to convert the mechanical energy from the turbine into AC electrical energy. The step-up transformer is operable to transfer the AC electrical energy at a lower voltage from the electric generator to a higher voltage. The converter is operable to convert the AC electrical energy at the higher voltage to DC electrical energy. The converter includes a converter leg for a phase of the AC electrical energy. The converter leg has an upper arm with a first plurality of sub-modules and a lower arm with a second plurality of sub-modules. Each sub-module is operable to function as a controlled voltage source.
