Abstract
An embodiment integrated common mode choke comprises a magnetic core, a magnetic plate, a first winding coil and a second winding coil. The magnetic plate is inserted within an inner circumference of the magnetic core. The first winding coil and the second winding coil are wound are wound in the same direction through the magnetic core. The integrated common mode choke is equivalent to a common mode choke and a differential mode choke connected in series. The inductance value of the differential mode choke can be changed by adjusting either the gap between the magnetic plate and the magnetic core or the thickness of the magnetic plate.
