A converter with at least one primary side having a first set of coils magnetically coupled to at least one secondary side having at least a second set of coils, wherein the primary side is electrically isolated from the secondary side by an isolation barrier, wherein one of the secondary sides is configured to be connected to an external output unit, wherein the primary side is magnetically coupled to another secondary side having a third set of coils which coils are configured to be coupled to an external input unit, wherein the two secondary sides are electrically isolated from each other by a second isolation barrier, wherein the three sets of coils are magnetically coupled to each other via a common magnetic path. The converter provides an isolated current-to-current transfer between the input side and the output side which replicates the input current with high accuracy. |
