Method of fabricating a high-frequency transformer
TL;DR: In this paper, a high-frequency transformer is constructed from a flexible circuit comprising a primary conductive film winding and one or more secondary conductive films windings disposed on a single dielectric membrane.
Proceedings ArticleDOI
Modeling of an LTCC Inductor Capable of Improving Converter Light-Load Efficiency
TL;DR: In this paper, a low profile power inductor fabricated using low temperature co-fired ceramics (LTCC) technology has been demonstrated to improve the light-load efficiency of a 5 V-to-1 V, 12.5 A buck converter operating with a switching frequency of 4 MHz, without the use of additional control circuitry.
Patent
Method of making conductive film magnetic components
TL;DR: In this paper, the conductive film is folded to form a stack of layers with each "layer" comprising part of a winding turn and with successive "layers" connected at the folds via the continuous conductive films.
Journal ArticleDOI
Modeling of magnetizing inductance and leakage inductance in a matrix transformer
TL;DR: In this article, a matrix transformer constructed from integrated core and z-folded flex circuits is described and the magnetizing inductance is derived using the reluctance method and exploiting structural periodicity and symmetry.
Journal ArticleDOI
Resonant Cross-Commutated DC–DC Converter
TL;DR: Parametric analysis is performed to study the impact of resonant components on voltage and current stresses in an interleaved two-phase buck converter with output voltage regulated by extended duty ratio.
