<p>The present invention is directed to system and method for current sensing. A current sensor system (10, 10a, 10b, 32, 60) includes a conductor (12, 12a, 36, 62, 80, 110) configured to receive current flow (14, 82) therethrough and generate magnetic flux (B1, 16, 20, 22, 88, 90, 92, 100, 102, 104, 120) thereabout. The current sensor system (10, 10a, 10b, 32, 60) also includes an anti-differential current sensor (H1, H2, 46, 48) configured to monitor magnetic flux (B1, 16, 20, 22, 88, 90, 92, 100, 102, 104, 120) about the conductor (12, 12a, 36, 62, 80, 110) and a flux concentrator (42, 44, 62, 64, 66, 94, 96, 98, 112, 114, 116) configured to concentrate magnetic flux (B1, 16, 20, 22, 88, 90, 92, 100, 102, 104, 120) induced by current flow (14, 82) through the conductor (12, 12a, 36, 62, 80, 110).</p> |
