ABSTRACT:
A current carrying wire is provided with a tubular shield construction which essentially covers the wire with conductive material, and preferably emulates a classical Faraday shield. The shield is formed of a multiplicity of insulated shield wires for minimized eddy current loss. When such a shielded wire construction is formed into a primary winding of a power transformer for a switching power supply, the secondary circuit is protected from electric shock hazards while enabling use of a gap free toroidal core for close coupling between primary and secondary windings. In another embodiment, such shields are used on both the primary and secondary windings of a matching transformer and are arranged for common mode rejection of noise associated with low power data signals.
