Abstract
An integrated common mode and differential mode inductor can include a first core including a first center leg, a second core including a second center leg, a first center winding on the first center leg, and a second center winding on the second center leg. The first center leg can be spaced apart from the second center leg, for example by a center air gap. The integrated common mode and differential mode inductor can further include a left winding on a first left leg of the first core and a second left leg of the second core, as well as a right winding on a first right leg of the first core and a second right leg of the second core.
