Description
|
|
PFC-chokes are one or two winding chokes with toroidal cores made of pressed soft magnetic powder material. The following materials are often used: - MPP (79%-81% Ni, 17 % Fe, 2%-4% Mo) - High Flux (50% Fe, 50% Ni) - Cool My, Sendust (FeSi9,6 Al5,4) These cores are usable over a wide range of permeability and have a smaller Lo/Ln factor at lower permeabilites than at higher permeabilities. PFC toroidal chokes are storage chokes for the application in active power factor correction circuits. Lamination chokes e.g. EI types are used in passive PFC circuits in contrary. This enables power factors of devicesor systems with a cos φ ≈ 1. The chokes are conform to EN 61000-3-2. They are suitable for high frequencies up to 150 kHz. The toroidal core is the ideal geometric shape for the magnetic flux, this results in a low magnetic stray field and low losses. The winding is constructed for low voltages and is wound with low stray field. The dimensions are determined by the energy E = 0,5 L I².
