摘要

先前，作者提出了一种低插入阻抗的非接触探针型电流传感器。本文阐明了该电流传感器在高频下的插入阻抗。然后，我们测量了流过GaN器件的实际高速开关电流，并将测量波形与同轴型分流电阻的波形进行了比较。对比测量波形发现，同轴分流电阻由于插入阻抗的影响在波形中出现振铃现象，而本文提出的电流传感器的振铃现象较少，表明测量对被测电路的损伤最小。

Ultra-Minimally Invasive Current Measurement in Fast Switching GaN Devices Using Optical Probe Current Sensor

Previously, the authors have proposed a contactless probe-type current sensor with low insertion impedance. In this paper, the insertion impedance of the proposed current sensor at high frequencies is clarified. Then, we measured the actual high-speed switching current flowing through a GaN device and compared the measured waveforms with those of a coaxial-type shunt resistor. Comparison of the measured waveforms showed that the coaxial shunt resistor exhibited ringing in the waveform due to the effect of insertion impedance, but the proposed current sensor exhibited less ringing, indicating that the measurement is minimally invasive to the circuit under test.
