  • Patent number: 11258386
    Abstract: A wind turbine assembly including a rotor system, a generator, a first converter, a second converter, and a controller system. The first converter includes a first bridge circuit having a plurality of switch members each having a controllable switch. The second converter includes a second bridge circuit having a plurality of switch members each having a controllable switch. The controller system is adapted to provide a drying operation for second converter including short circuiting the second converter with the controllable switches of the second bridge in circuit, and supplying power from the generator through the first converter to the short circuited second converter for drying the second converter.
