Abstract: A rotary joint includes a first part and a second part configured to rotate around a rotation axis against the first part. The first part has a first magnetic core and a capacitive data link component. The second part has a second magnetic core for coupling power with the a first magnetic core and a second capacitive data link component to transfer data from and/or to the first capacitive data link component. To weaken magnetic stray fields from the magnetic core, a resonant shield is provided outside the airgap between the magnetic cores. The resonant shield comprises an open ring shaped structure, having two open ends which are connected by a capacitor to form a resonant circuit.

Abstract: A power generating transformer system (PGTS) where the core of the transformer has one of the generalized configurations is presented. Also, a power factor correction method in a power generating transformer system (PGTS) and a PGTS functioning also as power supply are presented. A PGTS generates an AC voltage with the frequency which lets the desired relative phase which is the difference between the phase of the flux at the primary coil and that of the flux at the secondary coil be in a specified range. And by controlling the reactive power at the primary coil of the transformer of the transformer circuit or at the location where the AC voltage is generated, the power factor correction is done using one or more components in the transformer circuit (TC). Finally, block diagrams of PGTS are presented.

Abstract: A low-profile high minimum creepage housing for electronic components such as transformers is provided. The housing can include a body and a lid. The lid can have attachment members that secure the lid to the body, after an electronic component is installed into the body. The attachment members of the lid may also secure a wire routed along the outside of the body against the body. The lid may include protruding portions that extend into the body, thereby elongating a minimum creepage path.

Abstract: An electromagnetic device including an elongated electrical current conductor and a soft magnetic wire made of a soft magnetic material and having a helical section wound around the electrical current conductor for two or more turns, where the turns are free from physical contact with adjacent turns. The soft magnetic wire-farther includes a straight section joined to two ends of the helical section, and the straight section, can either, have a gap in it or be continuous without gaps. The electromagnetic device can be used as a current detector with a Hall-effect sensor placed in, the gap of the straight section, or as an inductor when the straight section is continuous, or as a transformer when a secondary electrical conductor winding is wound around the straight section that is continuous.

Abstract: High voltage DC generators based on a resonant tank include power inductors. As the demands on power output increase, but the demands on size of such high voltage DC generators decrease, the effect of radiated magnetic emissions become more significant. The present invention concerns a design for an inductive device, and a method for the assembly of an inductive device, in which a winding facing surface of the inductive device is a continuous portion, so that no air gap is present facing the winding facing surface. This reduces leakage of magnetic flux from the inductive device.

Abstract: 一种电磁感应器件及其制作方法，其中器件包括磁衣(110)和至少一组线圈(120)。磁衣(110)由两个以上的磁单元(111)组成，每个磁单元(111)内能够形成闭合的磁通回路，全部磁单元(111)拼合在一起形成为内部具有至少一个腔体(112)的基本封闭的整体，磁单元(111)彼此之间的分割面基本沿着磁通回路设置而不切断磁通回路。线圈(120)置于由磁衣(110)形成的腔体(112)中，线圈(120)的电极引出至磁衣(110)之外，磁衣(110)中的磁通回路由线圈(120)通电后形成。依据该电磁感应器件，一方面能够基本完全封闭线圈尽可能的避免漏磁，另一方面由于磁单元之间的分割面沿着磁通回路，因此在磁通回路上不会产生气隙，有效减小了磁阻。
