摘要： Generally, methods and processes for assembling magnetic components are presented herein. More specifically, conductors are wound around a substantially hollow bobbin. Portions of the conductors may be temporarily positioned outside the bobbin through slots in the flanges of the bobbin during the assembly process. Insulating layers may be wrapped around the conductors. The center legs of a pair of magnetic core halves may be inserted into the bobbin. The base of the magnetic core halves may have a passage to allow a conductor to pass therethrough at a height less than the height of the base.

摘要： Generally, a low-profile planar core structure for use in magnetic components and related processes are presented herein. More specifically, the planar core structure provides a relatively large winding area that reduces heat dissipation, reduces leakage inductance, and allows for a low-profile design. The planar core structure has a center core that is elongated along a horizontal axis. Furthermore, conductors may enter and exit the planar core structure without increasing its height.

摘要： Transformers having bobbins that are constructed in such a way that pre-formed secondary windings (e.g., resembling springs) may be slipped onto the bobbins after a primary winding has been wound onto the bobbin. Additionally, the secondary windings may also serve as a self-leading device. That is, they may not require terminations on pins of the bobbin, which may reduce cost and complexity. The secondary windings may have circular or non-circular (e.g., flat) cross-sections. The transformer winding techniques provided herein may reduce the number of components, and may promote smaller input filters and/or less filtering stages at a fraction of the cost of conventional transformers.

摘要： Magnetic structures for use in components utilized in switched mode power supplies can be combined to provide space and cost savings. Portions of magnetic cores can be utilized to form more than one component and/or separate magnetic cores can be combined into a single core. Further, a layer of material that has a higher flux density saturation point than the core and that is lower in permeability than the core (but higher than that of air) can be placed adjacent to the air gap in a core to decrease the magnetic flux passing through the vicinity surrounding the core so as to reduce EMI. A differential-mode choke and a separate common-mode choke can be combined onto a single core. An extra leg for a PFC choke core can be added to an isolation transformer core to form a single combined core. A pair of E-E core structures can be combined into a single core structure such as could be used to combine a pair of separate PFC chokes into an integrated pair of PFC chokes.

摘要： An inductive element including a magnetic core with a section received in a central opening defined in each of the layers in a multilayer circuit board. A primary winding, an auxiliary winding, and a secondary winding are each realized in conductive coils located on a plurality of layers in the circuit board. The secondary winding is separated from the other windings by a relatively-thick dielectric layer. Other dielectric layers separate each of the layers with the coils. EMI shields are provided on other layers. The coils are located in a central region of each layer so as to provide an adequate safety margin from the side edges of the inductive element.

摘要： We describe an inductive device for use in current shaping applications. The inductive device includes a core body comprising a first gap and a second gap, and at least one transition region between the first and second gaps. The shape of each gap in the inductive device can control a slope between two inductance values as a function of load current. The inductive device is capable of providing low total harmonic distortion (THD) AC output waveforms to achieve high efficiency.

摘要： Core structures that may be used in transformers to improve the number of turns-ratios available. The core structures may include at least three outer legs and a center leg. In operation windings of the transformer may be wrapped around the center leg (e.g., using a bobbin) a fractional number of times, such that the turns-ratio of the transformer may be more finely selected without increasing the number of turns required. Additionally, the outer legs may have different cross-sectional areas, such that even more fractional turns-ratios are available.

摘要： A conductive cable for reducing the power losses in components, such as inductors and transformers. The conductive cable includes multiple strands that each include an inner conductor and an outer insulating layer. The conductive cable includes strands of multiple cross-sectional areas (multiple gauges), such that the power losses associated with the skin effect may be reduced. The cross-sectional areas of the strands of the conductive cable may be selected dependent upon the frequency content of the current that they are intended to carry. In the case of a PFC boost converter, the various cross-sectional areas of the strands may be selected to carry the harmonics of and AC power source, as well as higher frequency current caused by a switch associated with the PFC boost converter.
