Abstract

Сердечник трансформатора или индуктора, выполненный из магнитного материала, имеет три стержня (6, 8, 10), сопряженных друг с другом посредством ярм. Сердечник содержит три петли (12, 14, 16) из проводов и/или лент из магнитного материала, причем каждая из петель образует часть двух стержней. Петли, образующие части двух различных стержней, выполнены с чередованием в пределах одного из стержней, общего для указанных петель. Такое выполнение придает сердечнику механическую стабильность и хорошие магнитные свойства.Международная заявка была опубликована вместе с отчетом о международном поиске.
