Patent number: 10170231Abstract: The present invention relates to a choke with two coils and a core for interleaved applications in step-up or step-down circuits or power factor compensation circuits. The core comprises several core sections with several lateral legs and a middle leg, whereby the core is designed such, that a coupling factor k of the two coils is smaller than 3%-5%. Furthermore, the core is designed such, that the core section form two loops with the middle leg as a common section, whereby each of the two coils lies on different loops outside of the common section. The lateral legs have a cross section A1 and the middle leg for the common section has a cross section A2<2×A1.Type: GrantFiled: March 31, 2015Date of Patent: January 1, 2019Assignee: Sumida Components & Modules GmbHInventors: Johann Winkler, Ernst Holzinger, Robert Ludwig, Iyad Kebaisy, Herbert Jungwirth
