Abstract: A discrete device in which a capacitive and inductive function has been integrated is comprised of at least two insulated amorphous ribbons which are spirally wound to form a cylindrical toroid. Each of the amorphous metal ribbons is insulated from each other ribbon by a dielectric layer and wound in a stacked configuration to provide the capacitive function. Two conductive windings are then wrapped around segments of the cylindrical toroid to provide inductive and/or transforming functions as desired. A magnetic circuit is formed through the windings by the amorphous metal ribbons. A dielectric insulating layer between the ribbons is offset from the longitudinal edge of the ribbon so that the longitudinal edge of each ribbon is exposed. One ribbon has its longitudinal edge exposed on one surface of the toroid while another ribbon has its longitudinal edge exposed on the opposing surface of the toroid.

Abstract: A discrete electromagnetic device in which the transformer/inductor function and a capacitive function are integrated is achieved by utilizing both the magnetic permeability and the dielectric constant of one or more soft ferrite layers. The device is comprised of a plurality of soft ferrite planar layers spaced apart in a stacked array. Between each soft ferrite layer is a metallic layer which forms one of the plates of the capacitor. A first and second set of apertures are defined through each of the planar ferrite layers. The first and second set of apertures are aligned among the plurality of ferrite layers so that a conductive element is led through one set of apertures to form a loop or coil. A similar conductive element or coil is led through the second set of apertures to form a second loop. The two loops thus serve as the secondary and primary of a transformer or alternatively as two inductors with the ferrite material acting as the magnetically permeable core.

Abstract: An inductor included as part of a pulse width modulation amplifier is formed by four coils 9A, 9B, 9C and 9D arranged alongside each other and connected in parallel. The coils are supported against electromotive forces tending to pull them together by insulating strips 10. The coils are enclosed within an electromagnetic shield formed by a cabinet 1. Because of the arrangement of the coils the magnetic field generated by them is confined to a region in the close vicinity of the coils, so that the losses which would otherwise occur as a result of the proximity of the shield or other cabinet are reduced to a minimum. Thus the efficiency of the inductor formed by the combined coils is greater than would be the efficiency of a single coil within the same cabinet, this latter arrangement being conventional.
