摘要： An inductor is disclosed, including a first wire, a non-conductive material, and a shell. The non-conductive material may cover the first wire, with a portion of each end of the first wire uncovered. The shell may include a top portion and a bottom portion and include at least one magnetized layer and at least one gap between the first portion and the second portion. The shell may also surround a portion of the non-conductive material.

摘要： An inductive device is disclosed, including a first wire coupled to a first terminal and to a second terminal, a non-conductive material surrounding the first wire, and a magnetic film. The non-conductive material spans the region from the first terminal to the second terminal. The magnetic film surrounds at least a portion of the non-conductive material between the first terminal and the second terminal. The first wire has a first amount of inductance.

摘要： An embodiment of a system is disclosed, including an inductor, a voltage regulating circuit, a load, and a current detecting circuit. The inductor includes a first wire, a second wire, and a third wire. The third wire is between, and may be inductively coupled to, the first wire and the second wire. The voltage regulating circuit is coupled to a first end of the first wire and a first end of the second wire. The voltage regulating circuit is configured to generate a first current through the first wire and a second current through the second wire. The load is coupled to a second end of the first wire and a second end of the second wire. The current detecting circuit, coupled to ends of the third wire, is configured to generate an output signal based on a third current through the third wire.
