Abstract
This invention discloses a monolithic inductor including a body made by compressing a magnetic powder, a coil positioned in the body, and a permanent magnet positioned in the body and in a magnetic circuit formed by applying current to the coil. The monolithic inductor of this invention includes the magnetic body containing the permanent magnet and the coil. The permanent magnet in the magnetic circuit (path of magnetic flux lines) formed by applying current to the coil generates a reverse-bias magnetic field, thereby increasing the operating range of the magnetic body, the saturation current of the magnetic body, and the rated current of the inductor.
