20090127857 | ELECTRICAL INDUCTOR ASSEMBLY - An electrical inductor assembly comprises an inductor core having a circular shape, a wire guide that surrounds the inductor core and includes a plurality of slots, at least one of the slots forming a path winding around the inductor core, and at least one wire placed in one of the plurality of slots to form a winding. A method of forming an electrical inductor assembly comprises forming an inductor core having a circular shape, surrounding the inductor core with a wire guide, winding at least one wire around the inductor core along a slot in the wire guide, and applying an insulating material to the slot containing the at least one wire to electrically insulate the at least one wire. | 05-21-2009 |
20090128273 | Inductor winder - An electrically insulating bobbin surrounds the magnetic core of an inductor. The bobbin includes a number of channels to receive wire for making an inductor. When wire is positioned in the channels, the wire is wound around the inductor core, but insulated from the inductor core and the other turns of wire. Because the bobbin insulates the turns of wire from each other and from the inductor core, bare rope wire can be used to wrap the inductor, resulting in reduced size and weight and improved ease of manufacture. | 05-21-2009 |
20090141419 | SYSTEM AND METHOD OF FILM CAPACITOR COOLING - Film capacitor assembly has a plurality of film capacitive layers for storing an electric charge. The plurality of film capacitive layers have a first metal contact and a second metal contact. A heat sink removes heat from the plurality of film capacitive layers. The heat sink is in thermal conductive communication with at least one of the first metal contact and the second metal contact. A dielectric material is configured to prevent a transmission of electric current through the heat sink from the plurality of film capacitor capacitive layers. | 06-04-2009 |
20100019862 | Lightweight Electromagnetic Interference Filter - A low pass filter includes a differential mode filter and a common mode filter. The common mode portion of the filter includes at least one inductor and one capacitor, as well as a damping circuit with at least one capacitor. The low pass filter has a reduced weight, which is useful in circumstances in which weight is a significant factor, such as in aircraft. | 01-28-2010 |
20130083574 | DUAL-INPUT NINE-PHASE AUTOTRANSFORMER FOR ELECTRIC AIRCRAFT AC-DC CONVERTER - A dual-input nine-phase autotransformer converts first and second three-phase AC inputs to a nine-phase AC output. The autotransformer includes input terminals for connection to a first three-phase AC input and a second three-phase AC input smaller than the first three-phase AC input. The autotransformer includes a first plurality of coils, a second plurality, and a third plurality of coils wound on respective phase legs of the autotransformer. The autotransformer includes a plurality of output terminals for providing a plurality of AC output voltages, and a plurality of internal terminals for connecting the first, second, and third plurality of coils in a configuration that provides a 40° phase shift in the AC outputs provided by the dual-input nine-phase autotransformer. | 04-04-2013 |
20130187738 | ELECTRICAL APPARATUS HAVING A THERMALLY CONDUCTIVE BOBBIN - An electrical apparatus includes a magnetic core, and a bobbin extending about and partially covering the magnetic core. The bobbin is formed from a thermally conductive material. An electrical conductor forms a winding that wraps about the bobbin. | 07-25-2013 |
20130272040 | DUAL-INPUT 18-PULSE AUTOTRANSFORMER RECTIFIER UNIT FOR AN AIRCRAFT AC-DC CONVERTER - A dual-input 18-pulse autotransformer rectifier unit for more electric aircraft AC-DC converter uses an autotransformer with a nine-phase output to condition AC power prior to DC rectifying the AC power. | 10-17-2013 |
20160042854 | HEAT TRANSFER IN MAGNETIC ASSEMBLIES - A magnetic assembly includes a winding and a housing disposed about the winding. The housing includes an interior surface contoured to conform to the winding to facilitate heat transfer between the winding and the housing. A method of manufacturing a magnetic assembly includes forming a contoured interior surface on a housing and assembling a winding into the housing such that the interior surface of the housing conforms to the winding to facilitate heat transfer between the winding and the housing. | 02-11-2016 |
