A wind turbine assembly comprising a rotor system (2), a generator (4), a first converter (61), a second converter (62), and a controller system (909). The first converter (61) comprises a first bridge circuit having a plurality of switch members each having a controllable switch. The second converter (62) comprises a second bridge circuit having a plurality of switch members each having a controllable switch. The controller system (909) is adapted to provide a drying operation for second converter comprising short circuiting the second converter (62) with the controllable switches of the second bridge circuit, and supplying power from the generator (4) through the first converter (61) to the short circuited second converter (62) for drying the second converter (62). 一种风力涡轮机组件，包括转子系统(2)、发电机(4)、第一转换器(61)、第二转换器(62)以及控制器系统(909)。第一转换器(61)包括第一桥接电路，该第一桥接电路具有各自带有可控开关的多个开关构件。第二转换器(62)包括第二桥接电路，该第二桥接电路具有各自带有可控开关的多个开关构件。控制器系统(909)适于提供用于第二转换器的干燥操作，包括通过利用第二桥接电路的可控开关来使第二转换器(62)短路，并且将来自发电机(4)的电力通过第一转换器(61)供应到经短路的第二转换器(62)，以
