Current disturbance detection system

A driving circuit for providing power generated by a converter to a load, the driving circuit comprising:

• an input adapted to receive power from the converter;
• output terminals adapted to connect to a load for providing the received power to the load;
• a fault detection inductor electrically connected in series with the output terminals so that a current flow through the output terminals and the load passes through the fault detection inductor, such that a fault across the output terminals causes a change in the current flow through the fault detection inductor;
• a first current sensing inductor through which a current provided by the converter passes;
• a feedback inductor galvanically isolated from and magnetically coupled to the fault detection inductor and configured to modify an electrical parameter through the feedback inductor responsive to the change in the current flow through the fault detection inductor, and also galvanically isolated from and magnetically coupled to the first current sensing inductor and is configured to modify an electrical signal through the feedback inductor responsive to the current flow through the first current sensing inductor via the electrical signal;
• a detector configured to detect the modification in the electrical parameter through the feedback inductor and generate a fault feedback signal responsive to the detected modified electrical parameter;
• and
• a current sensing circuit to sense current flowing through the first current sensing inductor via the electrical signal.
