Isolating transformer

A transformer system, comprising:

• a mounting member;
• a plurality of isolating transformers, each isolating transformer of the plurality of isolating transformers including:
• a first port including a first plurality of terminals;
• a second port including a second plurality of terminals;
• a core between the first port and the second port, the core having first and second ends with first and second core channels extending between the first and second ends;
• and
• first and second electrically separate conductive paths, the first conductive path connected in series to the first port and the second conductive path connected in series to the second port, the first and second conductive paths each including:
• a plurality of first tracks extending to one end of the core, ones of the plurality of first tracks extending from the first or second plurality of terminals;
• a pair of wires in the first and second core channel;
• and
• a curved second track interconnecting the pair of wires at an end opposite the one end of the core, the first and second core channels extending between the curved second track of the first conductive path and the curved second track of the second conductive path.

A method of manufacturing an isolating transformer, the method comprising:

• providing a substrate of electrically insulative material having opposite first and second edges;
• arranging on the substrate:
• a first port formed of first and second terminals spaced apart and adjacent to the first edge of the substrate;
• and
• a second port formed of third and fourth terminals spaced apart and adjacent to the second edge of the substrate;
• providing a core between the first and second port, the core having first and second channels in the core extending between opposite first and second ends of the core;
• forming first, second, third, and fourth tracks on the substrate extending to the core from the first, second, third, and fourth terminals, respectively, the first and second tracks extending from the first port are spaced from each other, and the third and fourth tracks extending from the second port are spaced from each other;
• forming a fifth track on the substrate between the core and the first and second tracks;
• forming a sixth track on the substrate between the core and the third and fourth tracks, the fifth and sixth tracks being curved;
• and
• providing a pair of twisted wires through the first and second channels in the core;
• wherein the pair of twisted wires, first, second, and sixth tracks form a first conductive path connected in series to the first port;
• and wherein the pair of twisted wires, third, fourth, and fifth tracks form a second conductive path connected in series to the second port, the first and second conductive paths being electrically isolated from each other.
