利用趋肤效应的双平行电流迹线宽带隧道磁阻电流传感器

In highly integrated switching circuits and power electronic converters, noncontact wideband current sensors are typically required for monitoring operational status. However, the magnetic field distribution of printed circuit board traces is influenced by the skin effect as the current frequency increases, which, in turn, affects the frequency characteristics of the sensor. In this study, we prop...
