Abstract

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.

使用共模滤波器扼流圈的宽带电流传感器
有专用的宽带电流互感器。然而,在本文中,对基于标准可用共模滤波器电感的电流传感器的特性进行了评估。根据电感和谐振频率,可以实现0.5 Hz到50mhz的频率范围。由于所使用的非晶材料具有非常高的磁导率,并且可以控制高频绕组的共振,因此可以实现这种性能。讨论了以下限制:由于低频和直流元件的饱和,由于负载电阻,由于涡流和插入的初级导体。

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. The EPE Journal is recognized as a truly European specialized Journal on power electronics, drives and applications of a very high scientific and technological level. The Journal is in close relation with the bi-annual EPE Conference, the leading European Conference in the field, which brings manufacturers, researchers and users together. Topics include, but are not limited to: -Application of control methods to electrical systems- Devices- Education- Electrical machines and adjustable speed drives- Measurements and sensors- Modulation strategies and specific control methods for static converter- Motion control and robotics- Power electronic system design & packaging- Power electronics and drives in aerospace and space- Power electronics and drives in surface transport- Power electronics converter circuits- Power electronics in generation, transmission and distribution of electrical energy- Power supplies- Systems engineering
