Latest Patents

One of his notable patents is the "Apparatus and method for PCB winding planar magnetic devices." This invention outlines a method and apparatus for laying out planar magnetic coils on a PCB. The design maximizes layer-to-layer overlap, thereby enhancing total inductance for the given layout area. By spiraling alternating layers inward and outward, the invention also allows for layer-to-layer electrical contacts within the magnetic field area. This feature reduces leakage inductance and minimizes the extra conductor line length needed for connections outside the magnetic field. The reduced conductor line length leads to lower conductor line resistance. This method is applicable to various devices, including voltage transformers, isolation transformers, and simple inductors.
