Abstract

The so-called delta-phi choke coil exploits the effects of various core materials and/or air gap sections in the core parts on the magnetization curves of the core materials. It comprises at least two magnetically separated core sections possessing different magnetic properties, on which at least one common coil is wound. When current flows through the coil, the core sections experience the same magnetic flux. The different magnetic properties give rise to different magnetic fields in the core sections, with which selected definable inductance behaviours can be obtained by suitable choice of dimensions. In the case of special definable inductance behaviours, the delta-phi choke coil must be equipped with additional core sections and/or additional coils incorporated in an additive and/or subtractive series circuit, in a parallel circuit and/or a combined circuit.
