A device for interconnecting electronic systems with respective reference potentials, the reference potentials being different from each other and separated by an alternating potential difference, the device comprising:
- a plurality of electrical connections configured for electrically connecting said electronic systems;
- inductance coils each placed in series in between said electrical connections, wherein said inductance coils are electromagnetically coupled and comprise windings arranged around a common ferromagnetic core;
- a source of alternating excitation voltage including a first end and a second end, said first end being connected directly, or indirectly through one of the inductance coils, to a floating reference potential of a first electronic system and said second end being connected directly, or indirectly through one of the inductance coils, to a ground reference potential of a second electronic system in such a way as to cause the floating reference potential to oscillate with respect to the ground reference potential.
A method for interconnecting electronic systems with respective reference potentials, the reference potentials being different from each other and separated by an alternating potential difference, the method comprising the steps of:
- establishing electrical connections for electrically connecting the electronic systems;
- inserting inductance coils, each of said inductance coils in series in between said electrical connections;
- connecting a source of alternating excitation voltage including a first end and a second end, said first end being connected directly, or indirectly through one of the inductance coils, to a floating reference potential of a first electronic system and said second end being connected directly, or indirectly through one of the inductance coils, to a ground reference potential of a second electronic system in such a way as to cause the floating reference potential to oscillate with respect to the ground reference potential;
- winding the inductance coils around a common ferromagnetic core;
- and
- establishing electromagnetic coupling between said inductance coils.
