摘要：An integrated circuit transformer (58) which is constructed in a laminar hion isdisclosed. The present invention includes a bottom plate (10) with cores (14) protrudingfrom its upper surface (13) and a top plate (16) with several feed through holes (18). Bothplates (10, 16) are made from high permeability magnetic material. Interposed betweenthe top and bottom plates (10, 16) are at least one primary (19) and at least onesecondary (40). The primary (19) has feed through holes (22), vertically aligned with thefeed through holes (18) in the top (16), holes (20) to allow the cores (14) to protrudethrough, and tabs (26, 28) for connecting to the input circuit. The primary (19) is made of alaminate clad with an electrical conductor. The circuit which conducts the current aroundthe cores is fabricated by etching special patterns of insulative gaps (24) into theelectrical conductor. The secondary (40) has holes (42) to allow the cores (14) toprotrude through. It also is made of a laminate clad with an electrical conductor. Andagain, the circuit which conducts the current around the cores is fabricated by etching aspecial pattern of insulative gaps (44) into the electrical conductor. The output circuit isconnected to the secondary at three connection points (48, 50, 52). These points areaccessible through the feed through holes (18, 22) and access holes (49, 51). The primary(19) and secondary (40) may be fabricated as a sub-assembly by multiple layer printed
circuit techniques. More than one primary (19) and secondary (40) may be utilized in theintegrated transformer (58). The transformer may be embodied as either a current, avoltage or a power transformer.
