ABSTRACT:
Galvanic isolation device for direct current electrical signals or electrical signals likely to include a direct current component, which includes a transformer (T), reversible switch I for chopping the incident signal applied to one wind of this transformer reversible switch I' for chopping the signal obtained at the other winding of this transformer, controlled either in phase or in phase opposition with each other and filters (F1,F2) for filtering the chopped signals respectively obtained at windings of the transformer.
