Abstract: An integrated transformer and an electronic device are disclosed. The integrated transformer includes at least one first base plate and at least one second base plate. Each of the first and second base plate defines multiple annular accommodating grooves. The annular accommodating grooves divide each of the first and second base plate into multiple central parts and a peripheral part Each central part defines multiple inner via holes there through. The peripheral part defines multiple outer via holes there through. The integrated transformer further includes multiple magnetic cores disposed in the respective annular accommodating groove and transmission wires disposed on both sides of the first and second base plates. Transformers and the filters are arranged on two base plates respectively, and the thickness of the transmission wire layers of the filters is less than that of the transformers. Thus, the structure of the electromagnetic device may be more compact.

Abstract: Disclosed are apparatus and methods for embedded high voltage transformer components. Industrial applications require transformers that provide high voltage isolation. The laminate materials used for fabricating Printed Circuit Boards (PCB) are very good insulators and PCB transformers can provide higher voltage isolation than traditional wire wound devices. There are a variety of PCB laminate materials with different properties for voltage breakdown. FR-4 laminate is commonly used and has voltage breakdown properties exceeding 10 kV/mm. To produce PCB transformers with breakdown voltages exceeding 5 kV, it is beneficial to use laminate with much higher breakdown voltages. Generally, the materials with high breakdown voltage cost more. High voltage isolation can be achieved at a moderate cost by mixing low cost FR-4 laminate with high voltage dielectric materials.
