Abstract

Изобретение касается силового трансформатора или индуктора. Обмотка (31) трансформатора/индуктора образована гибким проводником (38), имеющим средство удержания электрического поля, заставляющее электрическое поле, возникающее под влиянием электрического тока в обмотке (31), удерживаться внутри изоляционного слоя гибкого проводника (38). Толщину изоляционного слоя гибкого проводника (38) выбирают таким образом, чтобы электрическое напряжение (33) было постоянным по всей длине обмотки. Площадь поперечного сечения изоляционного слоя гибкого проводника (38) таким образом оптимизируется, обеспечивая высокий коэффициент заполнения конструкции трансформатора/индуктора.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a power transformer or inductor. The transformer / inductor winding (31) is formed by a flexible conductor (38), which has a means of holding the electric field, forcing the electric field generated by the electric current in the winding (31) to be kept inside the insulating layer of the flexible conductor (38). The thickness of the insulating layer of the flexible conductor (38) is chosen so that the voltage (33) is constant along the entire length of the winding. The cross-sectional area of the insulating layer of the flexible conductor (38) is thus optimized, providing a high fill factor for the transformer / inductor structure. The international application was published along with an international search report.
