IMPROVEMENTS IN PLANAR TRANSFORMERS

A planar transformer comprises a plurality of conductive windings provided by at least one PCB and linked by a common ferrite core passing through the or each PCB. The transformer windings are at least partially magnetically shielded from the ferrite core by a conductive non-continuous shield formed...

Zusammenfassung:A planar transformer comprises a plurality of conductive windings provided by at least one PCB and linked by a common ferrite core passing through the or each PCB. The transformer windings are at least partially magnetically shielded from the ferrite core by a conductive non-continuous shield formed by copper planed areas on one or more of the PCB layers to improve the coupling between the windings.
