摘要： An electromagnetic device and a high-voltage generating device which are thin and improved in the characteristics are provided in which a magnetic core 3 is made of a cylindrical form of a ferrite material having a higher intrinsic resistance. A winding is provided by winding a flat rectangular wire conductor 2 in an edge-wise winding form directly on substantially the entire length of the magnetic core 3. As any insulator such as a coil bobbin is not needed between the flat rectangular wire conductor 2 and the magnetic core 3, the winding can be decreased in the overall size or thickness thus contributing to the dimensional reduction of the electromagnetic device. Also, as its flat rectangular wire conductor 2 is wound directly on the magnetic core 3, the winding can be minimized in the length and thus the overall resistance. Moreover, as there is no gap between the winding and the magnetic core 3, the self-inductance can be reduced while the size and the number of turns of the winding remain unchanged.
摘要翻译：提供一种电磁装置和高电压产生装置，它们的特性薄且改进，其中磁芯3由具有较高固有电阻的铁氧体材料的圆柱形形成。通过在平坦的方形线状导体2上直接在磁芯3的基本上整个长度上缠绕边缘绕组形式来提供绕组。由于扁平矩形导体2和磁芯3之间不需要诸如线圈架之类的绝缘体，所以可以减小绕组的整体尺寸或厚度，从而有助于电磁装置的尺寸减小。此外，由于扁平矩形导体2直接缠绕在磁芯3上，所以绕组的长度可以最小化，从而使整体电阻最小化。此外，由于绕组和磁芯3之间没有间隙，因此绕组的尺寸和匝数保持不变，可以减小自感。

摘要： A magnetic and electrical circuit element including magnetic-flux-conducting posts, and a multi-layer structure formed with an electrically-conductive material. The multi-layer structure includes multiple layers forming a stack of layers along a length of the posts, said multi-layer structure configured as primary and secondary windings of a transformer. The primary winding is embedded in the multi-layer structure and wound around the magnetic-flux-conducting posts in such a way that a magnetic field induced in each of the magnetic-flux-conducting posts has a magnetic field polarity opposite to a polarity of the respective magnetic field of the magnetic-flux-conducting post adjacent the respective magnetic-flux-conducting post. Around each of the magnetic-flux-conducting posts, there is a respective one of the secondary windings connected to a semiconductor device. The magnetic-flux-conducting posts are connected magnetically by continuous magnetic-flux-conducting plates, each of which is shaped to ensure a continuous flow of the magnetic field successively through adjacent magnetic-flux-conducting posts.
