摘要： A pitch control system for a wind turbine is disclosed. The pitch control system may generally include a motor having an armature and a winding and a grid power source configured to supply electrical power to the motor. The pitch control system may also include a plurality of switching components configured to control a first current through the armature independent of a second current through the winding. In addition, the pitch control system may include an auxiliary switching component electrically coupled between the grid power source and at least a portion of the switching components. The auxiliary switching component may be configured to be opened when a grid voltage of the grid power source exceeds a first voltage threshold.

摘要： Methods of making multi-layer light-emitting devices and related components and systems are disclosed. The light-emitting devices can include a layer of reflective material bonded with a layer of p-doped material. The reflective material can be capable of reflecting at least about 50% of light generated by a light-generating region that impinges on the layer of reflective material.

摘要： The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.
