磁阻/罗氏线圈可用作电力电子转换器中的宽带非接触式电流传感器。然而，由于集肤效应，这些传感设备检测到的磁场随频率变化。本文研究了两种使用导电板和功率迹线的磁场集中 (MCON) 技术。这些 MCON 导致传感元件在感兴趣的频率范围内看到更均匀的磁场。仿真和实验结果证明了所提出的 MCON 的有效性及其对传感器性能的影响。
Magnetoresistor/Rogowski coil can be utilized as a wideband contactless current sensor in power electronic converters. However, the magnetic Field detected by these sensing devices varies with frequency due to skin effect. This paper presents an investigation on two Magnetic field Concentration (MCON) techniques using conductive plates and power trace. These MCONs result in a more uniform magnetic Field seen by the sensing elements over the frequency range of interest. Simulation and experimental results are presented to demonstrate the efficacy of the proposed MCONs and their impacts on performance of the sensors.
