High voltage hold-off coil transducer

摘要

Disclosed herein are various embodiments of coil transducers configured to provide high voltage isolation and high voltage breakdown performance characteristics in small packages. A coil transducer is provided through and across which data or power signals may be transmitted and received by primary and secondary coils disposed on opposing sides thereof without high voltage breakdowns occurring therebetween. A central core layer separates the transmitting and receiving coils, and has no vias disposed therethrough. At least portions of the coil transducer are formed of an electrically insulating, non-metallic, non-semiconductor, low dielectric loss material.

1. A coil transducer, comprising:
a generally planar dielectric barrier and electrically insulating core structure having upper and lower surfaces and comprising a central core layer, an upper core layer disposed above the central core layer and a lower core layer disposed below the central core layer, each of the central, upper and lower core layers comprising an electrically insulating, non-metallic, non-semiconductor, low-dielectric-loss material; a first electrically conductive coil disposed within, upon or near the upper surface of the core structure; a second electrically conductive coil disposed within, upon or near the lower surface of the core structure; an input lead frame; an output lead frame; wherein the central core layer has no vias disposed therethrough or therein in a region of the central core layer disposed directly between the first coil and the second coil, the first and second coils are spatially arranged and configured respecting one another such that at least one of power and data signals may be transmitted by the first coil to the second coil across the portion of the central core layer containing no vias, the central core layer has a thickness ranging between about 0.5 mils and about 8 mils, electrical connections to both of the first and second coils are established through one only of the upper surface and the lower surface, and the input and output lead frames are operably connected to the coil transducer.
