Embodiments of the present disclosure provide for methods and devices for improving the heat dissipating properties of a heatsink to provide increased cooling for electronic equipment, such as power converters. In one embodiment, a heatsink includes at least one fluid cooled portion and at least one heat pipe disposed adjacent to the fluid cooled portion. The heat pipe improves the conduction of heat away from heat sources.

Method and apparatus for cooling electronics

A method for controlling a pitch control system of a wind turbine includes providing a charged backup battery configured to supply no energy to a DC link when full AC input power is available, wherein the DC link includes a DC link capacitor. The method further includes using energy stored in the DC link capacitor to operate a pitch control system during a loss or dip of AC input power, and maintaining charge on the DC link capacitor using the charged backup battery as voltage across the DC link capacitor drops during the operation of the pitch control system.

Pitch control battery backup methods and system

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.

Method and apparatus for gravity induced thermal energy dissipation

A ferrite assembly has a first conductor and a number of ferrite members. Each of the number of ferrite members has a core. The ferrite members are in electrical communication with the first conductor. The ferrite assembly has a number of current dividing members in electrical communication with the first conductor. The current dividing members define a number of passages for allowing an airflow therethrough.

Ferrite assembly

A method for powering a pitch motor drive system for at least one DC pitch motor of a wind turbine includes rectifying a voltage using a bridge circuit to thereby supply a DC link voltage to a bridge comprising active switching devices, and utilizing at least one link capacitor to smooth the DC link voltage and act as an energy sink and source for the DC pitch motor or motors.

Methods and apparatus for pitch control power conversion

A method and apparatus for an air core reactor including a plurality of straight members and a plurality of offset members, the plurality of straight and offset members are interconnected to form an orthogonal spiral having an air core therethrough.

Fabricated air core reactor

An apparatus and method for mounting electrical devices in a housing at an angle relative to the ground is provided. The apparatus comprises a housing having a top, bottom, and sides, each of which may be open, closed or ventilated. One or more electrical devices are located in the housing and are oriented at an angle relative to the horizontal ground. The electrical devices may be silicon controlled rectifiers that serve as a power bridge between an exciter and a power generator. A method for mounting electrical devices in a housing at an angle relative to the horizontal ground is also provided.

Series-parallel fans system

An apparatus and method for providing a supply of air to cool electrical devices is provided. The apparatus comprises a two fan housings, each containing a number of fans arranged to blow air in a parallel fashion. The exhaust of one housing is connected to the intake of the other housing by a balancing plenum. The apparatus provides a sufficient supply of cooling air when one or more of the fans is inoperable. The device being cooled may be the power bridge of an exciter for a power generation system. A method for providing a supply of air to electrical devices is also provided.

Series-parallel fan system

A system for temperature control of an electronic component includes a heat plate supporting the component; a heat plate temperature sensor; a fan capable of providing air for cooling the heat plate; and a fan control for using the heat plate temperature to control the operation of the fan to provide a substantially constant heat plate temperature. The system can further include a heat pipe assembly having fins and coupled to the heat plate with the fan capable of providing air to the fins. The heat pipe assembly can include at least two heat pipes each having first ends coupled to the heat plate and second ends situated in a condensation section where at least one of the heat pipes has a different working fluid than an other. A switch temperature or load current sensor can be coupled to the heat plate and supply data to a switch controller for receiving the switch temperature, determining whether the temperature or load current has changed, and adjusting a switching frequency of the at least one electronic switch device in response to any change of the switch temperature. A bus layer can be situated adjacent the component and selectively coated with an insulating material and studs can mechanically and electrically coupling the bus layer and a printed circuit board to the component. An insulating shield can be situated between the bus layer and the printed circuit board with the studs.
