Latest Patents
Don V Folker holds a patent for an "Integrated-magnetic filter having a lossy shunt." This invention features a two-winding, integrated-magnetic EMI filter that provides damped common-mode and differential-mode inductances. The preferred embodiment of the filter incorporates a magnetic core structure that includes a high-permeability C-core, a high-permeability I-core, and a low-permeability, lossy shunt. The assembly of these core pieces forms a structure similar to an E-I configuration, which has two winding windows. The lossy shunt aids in dissipating noise and diminishes the effects of unwanted parasitic resonances by providing damping for the differential-mode inductance. Additionally, the C and I core pieces contribute to damping the common-mode inductance. By varying the reluctance of the shunt, the differential-mode inductance can be adjusted separately from the common-mode inductance, allowing for tuning of the filter to eliminate specific noise frequencies.
