High Voltage Hold-Off Coil Transducer
First Claim
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 above the core layer, and a second electrically conductive coil disposed below the core layer;
wherein the core layer has no vias disposed therethrough or therein and 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 core layer.

Abstract
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.
