kernesaturation
Core saturation, or kernesaturation, is a magnetic phenomenon in which the magnetic core of a transformer or inductor reaches the limit of its magnetization. As the flux density B approaches the material's saturation flux density Bsat, the incremental permeability drops, causing the inductance to fall and the magnetic circuit to lose its linearity.
Mechanism: In ferromagnetic materials, magnetic domains align with the applied field. At low flux levels, domain
Consequences: When saturation occurs in a transformer or inductor, the inductance becomes current-dependent and non-linear. This
Occurrence and design considerations: Saturation is more likely under high peak currents, DC bias, low operating
Measurement and modeling: Core behavior is described by B-H curves and energy-storage characteristics. Designers use nonlinear
