摘要： A toroidal inductor (100) and method of forming same. The invention is intended to decrease the direct current resistance (DCR) of the toroidal inductor circuit. Thus, an increase in the quality factor (Q) of the circuit is produced. The toroidal inductor includes a coil formed from an elongated conductor extending around a core material and defining a plurality of turns. The elongated conductor is comprised of one or more coil segments. The coil segments are arranged in an alternating pattern of a first type segment (101) and a second type segment (102). Each of the coil segments of the first type includes a plurality of elongated parallel conductors (104, 105) spaced apart and electrically connected by conductive links (108) at predetermined intervals along their respective lengths. The coil segments of the second type are formed of a single conductor defined by a conductive via (302, 304) formed in the substrate.

摘要： An embodied step-up toroidal transformer (100). The step-up toroidal transformer (100) includes a plurality of coil segments (102, 104, 106, 108). Each primary coil segment (102, 104, 106, 108) is separately comprised of a plurality of turns of an elongated conductor coiled around a toroidal shaped core (120). The plurality of primary coil segments (102, 104, 106, 108) are collectively disposed around a circumference defined by the toroidal shaped core (120). Each of the plurality of primary coil segments (102, 104, 106, 108) is electrically connected in parallel across a first primary input terminal (128) and a second primary input terminal (130). The step-up toroidal transformer (100) also includes a secondary winding (126) formed from a plurality of turns of a second elongated conductor coiled around the toroidal shaped core (136).

摘要： A toroidal inductor, including a substrate (100), a toroidal core region (434) defined within the substrate, and a toroidal coil including a first plurality of turns formed about the toroidal core region and a second plurality of turns formed about the toroidal core region. The second plurality of turns can define a cross sectional area (440) greater than a cross sectional area (442) defined by the first plurality of turns. The substrate and the toroidal coil can be formed in a co-firing process to form an integral substrate structure with the toroidal coil at least partially embedded therein. The first and second plurality of turns can be disposed in alternating succession. The toroidal core region can be formed of a substrate material having a permeability greater than at least one other portion of the substrate.

A first plurality of conductive traces (110) forming an electrical connection between substantially adjacent ones of the first and second plurality of conductive vias is formed on a first surface (106) of the ceramic substrate. Further, a second plurality of conductive traces (110) forming an electrical connection between circumferentially offset ones of the first and second plurality of conductive vias is formed on a second surface of the ceramic substrate opposed from the first surface to define a three dimensional toroidal coil.
