Abstract: An electric coupler includes a body, a first electrical path through the body having a first resistance to electric current within a first frequency range and a second electrical path through the body having a second resistance to electric current within a second frequency range.

Abstract: A method of assembling a housing assembly is provided. The method includes providing a housing that includes an access panel and a cavity defined therein, wherein the housing is sized to enclose at least one electrical system within the cavity. A portion of the housing is enclosed with a cover such that the access panel remains accessible and the cover is positioned against the portion of the housing. At least one gasket is coupled between the housing and the cover such that a seal is formed on the housing assembly that substantially prevents fluid from entering the housing assembly.

Abstract: A method and transfer circuit topology for a redundant power converter for switching a load between power conversion circuits in a redundant system. The transfer circuit topology includes a first contactor and a second contactor each having an input coupled to a source and an output coupled to a controlled commutating current path. The controlled commutating current path is coupled to the load for switching between the redundant power converters without interrupting current to the load.

Abstract: A rotor for a wind turbine generator includes a rotatable hub forming a cavity. A plurality of rotor blades is connected to the hub. A heat sink is at least partially positioned within the cavity and extends along a portion of a corresponding rotor blade. The heat sink includes a bottom surface mounted on a thermal energy generating component of the wind turbine generator. An opposing top planar surface includes a plurality of pins extending therefrom. The pins form an air flow path through the pins to dissipate the generated thermal energy from the thermal energy generating component.

Abstract: An apparatus for cooling electrical protective devices comprises an electrical protective device mounted to at least one electrical terminal, wherein the electrical terminals are cooled to indirectly cool the electrical protective devices. A pressurized coolant source passes a coolant fluid through coolant passages attached to the electrical terminals, thereby cooling the electrical terminals. The cooled electrical terminals maintain the temperature of the electrical protection device within an appropriate operating temperature range. This cooling method may be used to increase the fuse power rating of a fuse array while maintaining electrical coordination between the fuses in the fuse array and electrical devices protected by the fuse array.
