| 20100109648 | Current sensing inductor and a circuit thereof - An inductor design having a detection winding which is magnetically coupled to the existing winding and its induction voltage is used to cancel that of the existing winding. Having the induction voltage cancelled, the voltage across the existing winding represents a resistive voltage drop of the existing winding current. The detection winding is furthermore built with a non-inductive portion having a significantly higher DC resistance in proportion to that of the existing winding. This resistance proportion is insensitive against temperature variations when both the existing and the detection windings are built with the same material and subjected to the same environment. A reference current is fed through the detection winding to produce a reference resistive voltage drop which is used to cancel the resistive voltage drop across the existing winding. When a precise cancellation occurs, the existing winding current is known to be in exact proportion to the reference current. | 05-06-2010 |
