摘要： Aspects of the present disclosure are generally directed to a multi-rotor turbine having with a common line-side converter (LSC) (DC to AC converter) for each of a plurality of machine-side converters (AC to DC converters). For example, the multi- rotor turbine may include a plurality of machine-side converters (MSC), each configured to receive an alternating current (AC) input signal from one of a plurality of rotors of the multi-rotor turbine and generate a DC signal based on the input AC signal. The multi-rotor turbine may also include a line-side converter (LSC) configured to receive the DC signals from each of the plurality of MSCs and generate an output AC signal based on the DC signals.

摘要： A wind turbine (30) includes a support structure (12) and at least one energy generating assembly (32) having central structures along an axis of rotation such as a rotor hub (40) and a nacelle (46), which may enclose a generator (44) for transferring rotations of the hub (40) and wind turbine blades (42) extending from the hub (40) and caused by airflow into electrical energy. One of the central structures includes an aft end (50) defining a corrugated profile (34) with a plurality of lobes (36). Airflow over these lobes (36) generates powerful flow vortices which help mix out the wake flows downstream from the wind turbine (30). A method of using the lobes (36) for reducing a wake region downstream of the wind turbine (30) is also disclosed.
