The investigation of choking-coils characteristics in a wide range of current and frequency
Abstract:
Streszczenie:
In the paper the problem of measuring choking-coils characteristics in a wide range of a dc component of current and frequency is considered. Disadvantages of classical bridge methods are discussed and the manner of measurements of dependences of the module and the phase of the choking-coil impedance on a dc component of the current on inductance and frequency is described. The accuracy of this manner is discussed. Some results of measurements of the considered characteristics of choking-coils containing ferromagnetic cores made of different materials are shown. On the basis of the obtained results of investigations the ranges of current and frequency, in which each of the considered choking-coils has the best exploitive properties, are shown.
