  • Power electronics assembly having a potted high voltage attenuator card for a wind turbine
    Patent number: 11664715
    Abstract: A power electronics assembly for a power generation system includes a housing and an attenuator card positioned within the housing. The attenuator card may include at least one printed circuit board for a high-voltage attenuator circuit. The power electronics assembly also includes a potting material at least partially filling the housing on one or more sides of the attenuator card, a detachable end cap positioned at a first end of the housing, and multi-phase wiring communicatively coupled to the high-voltage attenuator circuit through the end cap.
    Type: Grant
