COUPLED INDUCTOR

摘要

A coupled inductor includes a magnetic core, a first and a second coil. The magnetic core has a top and a bottom surface. The first coil, located in the magnetic core, has a first coil input end and a first coil output end, and is wound around a first axis in a first winding direction from the first coil input end and extended to the first coil output end. The second coil, located in the magnetic core, has a second coil input end and a second coil output end, and is wound around a second axis in a second winding direction, opposite to the first winding direction, from the second coil input end and extended to the second coil output end. An orthographic projection of the first coil on the top surface is at least partially overlapped with that of the second coil on the top surface.

主权项

1. A coupled inductor, comprising:
a magnetic core having a top surface and a bottom surface opposite to each other; a first coil located in the magnetic core and having a first coil input end and a first coil output end, the first coil being wound around a first axis in a first winding direction, the first coil being wound from the first coil input end and being extended to the first coil output end, and the first axis passing through the top surface and the bottom surface; and a second coil located in the magnetic core, separated from the first coil, and having a second coil input end and a second coil output end, the second coil being wound around a second axis in a second winding direction, the second coil being wound from the second coil input end and being extended to the second coil output end, the second axis passing through the top surface and the bottom surface, the first winding direction being opposite to the second winding direction, and an orthographic projection of the first coil on the top surface being at least partially overlapped with an orthographic projection of the second coil on the top surface.
