ELECTRONIC TRANSFORMER/INDUCTOR DEVICES AND METHODS FOR MAKING SAME

摘要

The present invention relates to transformer inductor devices and to the methods of construction for inductive components such as inductors, chokes, and transformers. Plural via holes 12 are formed through a ferromagnetic substrate 10 . Primary 32 and secondary 34 conductors are placed through common vias to form a plurality of cell transformers have a 1:1 turns ratio. Circuits connect these primary and secondary winding in parallel and serial combustion to provide a transformer having the desired turns ratio.
