Application Of Ferrite Layers In Low Profile Oled Drivers

Tional magnetic devices the windings of planar transformers and inductors are located on flat sur faces extending outward from the core centerleg.

Planar inductor ferrite. The first applications for planar e cores were in power conversion. Correspondingly material grades were medium and high frequency power ferrites. Planar inductors using nizn ferrite thin plates are successfully applied to a 10 w class buck converter operated at 2 mhz.

If you have a planar coil with a ferrite block next to it the increase in inductance would likely be less than a factor of 2 higher than the coil without ferrite. One of the first papers published on planar magnetics was by alex estrov back in 1986. The inductance of the mains filter choke can be increased by substituting the power ferrite for a high permeability grade.

Pq26 series planar inductors are fixed power inductors wferrite core available in surface mount smt or through hole tab tht mounting style. Ac resistance of planar power inductors and the quasidistributed gap technique jiankun hu and charles r. Used in switching power supplies dcdc converters fpga and lowhigh profile current high current pol converters feedback control overload sensing load drop and shut down detection.

Our planar inductors are fixed standard power inductors wferrite core used in switching power supplies dcdc converters fpga and lowhigh profile current high current pol converters feedback control overload sensing load drop and shut down detection. Sullivan member ieee abstract low ac resistance planar or foil wound inductors constructed using a quasidistributed gap comprising multiple small gaps that approximate a distributed gap are analyzed. Planar transformers can be used in forward push pull and full bridge half bridge topologies at frequencies from 100 khz to 500 khz.

New planar construction alternatives for blending various power magnetic components of switchmode power processing circuits and systems are based on the use of core designs with multiple winding areas and core sections providing common flux paths for transformer and inductor operations. Magnetic cores used with planar devices have a different shape than conventional cores used with helical windings. After reviewing this paper you really get a feeling of what he accomplished.

A whole new learning curve can be seen on low profile ferrite cores and printed circuit boards if one is going to do any planar transformer designs. Click here for a summary of our newest planar transformers and a detailed description for determining losses and overall efficiencies.
