AC resistance of planar power inductors and the quasidistributed gap technique.

AC resistance of planar power inductors and the quasidistributed gap technique.

Low-AC-resistance planar or foil-wound inductors constructed using a quasidistributed gap comprising multiple small gaps that approximate a distributed gap are analyzed. Finite-element simulations are used systematically to develop a model broadly applicable to the design of such quasidistributed ga...
