Wide-band current transducers using common mode filter chokes
Dedicated wide band current transformers exist. However, in this paper, an evaluation is made of the characteristics of a current transducer based on a standard available common mode filter inductor. Based on the inductance and resonance frequency, a frequency span of 0.5 Hz up to 50 MHz can be achieved. The performance is possible by the fact that the used amorphous materials have a very high permeability and that the resonances of the windings at high frequency can be controlled. The following limitations are discussed: by saturation at low frequency and DC components, due to the load resistance, due to eddy currents and of the inserted primary conductor.
期刊介绍：
The scope of the EPE Journal is to supply all experts in the field of power electronics and drives, with the most recent information on the rapid evolution in the field of power electronics, drives and industrial applications.
Alongside contributions from scientists, the Journal also wants to attract contributions from those who are designing and producing power electronics systems and those who are involved in the applications of those systems in industrial processes.
In addition to original research articles, information is supplied on new products, industrial developments, company portraits, the EPE Association as well as international organizations such as the European Commission.
