    Abstract: The present disclosure relates to a switching semiconductor device. The switching semiconductor device of the present disclosure comprises a semiconductor device, a first heat dissipation plate configured to facilitate heat dissipation of a surface of the semiconductor device at an installation space, and a second heat dissipation plate disposed inside the installation space along a thickness direction of the first heat dissipation plate. The installation space is formed in a predetermined size at the surface of the semiconductor device, and the second heat dissipation plate is configured to contact the first heat dissipation plate so as to allow heat exchange. Accordingly, a heat dissipation area may be increased without increasing a size of the installation space.

    Abstract: A planetary gear assembly included in a washing machine driving system according to an embodiment of the present disclosure, may include a carrier shaft fixedly supported on a back end of a drum shaft by a first fastening member; a coupling shaft including a first shaft portion inserted into the carrier shaft and a first flange portion fixed to a back end of the carrier shaft by a second fastening member, and fixedly supported on the carrier shaft; a carrier including a second shaft portion inserted into the first shaft portion of the coupling shaft and a second flange portion positioned at a back side of the first flange portion of the coupling shaft, and fixedly supported on the coupling shaft; a sun gear rotationally supported on the coupling shaft and fixedly supported on a rotor frame of a motor by a third fastening member; a plurality of pinion gears coupled to the second flange portion of the carrier, and tooth-coupled with the sun gear; a ring gear tooth-coupled with the plurality of pinion gears; and a gear housing accommodating the sun gear, the plurality of pinion gears, and the ring gear therein. According to this configuration, since the sun gear, which is related to the reduction ratio of the planetary gear assembly, is coupled to the carrier coupled to the drum shaft, and the planetary gear assembly and the clutch are disposed in the inner space of the stator, it is possible to compact the washing machine driving system and to secure the maximum volume of the drum.
