PCB Embedded Transformer for Isolated DC-DC Power Supplies

In general, magnetic components can be considered as the bulkiest components required for power converters. In order to pursue with the miniaturization as one of the key factors in power electronics, a novel concept shows a transformer that represents embedding (integration) of the magnetic material into the inner layers of the PCB. By having magnetic com-ponent(s) integrated in the PCB, it is possible to further decrease the size of the footprint as well as the height of the total converter. This paper presents the design, simulation, manufacturing and the test results gained from a DC-DC converter module with a PCB embedded transformer.
