Thin film inductor and power conversion circuit
A thin film inductor is disclosed, which includes a thin film magnetic core. The thin film magnetic core includes at least one magnetic thin film. In each magnetic thin film, at least one type-1 gap is provided. A length direction of the type-1 gap is parallel to a direction of hard magnetization of the magnetic thin film. If the thin film magnetic core comprises at least two magnetic thin films, the at least two magnetic thin films are laminated and overlap each other. A sum of widths of all type-1 gaps in each magnetic thin film is the same.
System for manufacturing an inductor core
A system includes a magnetic material supply for regulating a magnetic material flow rate of a magnetic material and a binder material supply for regulating a binder material flow rate of a binder material. A nozzle is configured for depositing a deposition mixture of the magnetic material and the binder material on a surface and a preheater is configured to preheat the deposition mixture before depositing on the surface. A controller is in operative communication with the magnetic material supply, the binder material supply, and the preheater. The controller is configured to receive an inductor core design file that represents a geometry and a magnetic permeability distribution of an inductor core, move the nozzle to one or more deposition locations, and adjust the magnetic material flow rate to the binder material flow rate to achieve a deposition mixture having a desired magnetic permeability at the deposition locations.

An inductor includes a first conductor, a second conductor, an insulation film, and a magnetic body. The first conductor spirally extends in a plane. The second conductor spirally extends in a plane. The second conductor is stacked on and joined to the first conductor. The insulation film covers a surface of the first conductor and a surface of the second conductor. The magnetic body covers a surface of the insulation film and embeds the first conductor and the second conductor. The first conductor and the second conductor are connected to form a helical coil.
Multilayer board and method of manufacturing the same
A method of manufacturing a multilayer board includes forming conductor patterns on four or more insulating base material layers, forming a multilayer body by stacking the insulating base material layers in a state in which the conductor patterns face each other with prepreg layers therebetween, and heat-pressing the multilayer body. In a state before the step of heat-pressing, among the prepreg layers, a thickness of an outermost prepreg layer is larger than a thickness of a prepreg layer other than the outermost prepreg layer.
