Abstract
In one general aspect, a galvanic isolator is disclosed. It includes an isolation circuit with at least two diodes placed back-to-back between the input line and the output line. A leakage current detection element is provided between the input line and the output line. A protection circuit is operatively connected to the leakage current detection element.
