Abstract

The Van Veen loop is intrinsically well adapted to time-domain measurements of net magnetic dipole moment. That is, the system comes very close to preserving the shape of the time-domain waveform of the net or residual magnetic dipole moment produced by the DUT. This property makes the Van Veen Loop very useful in the characterization of magnetic field wireless power transfer systems in which short-time-scale features such as ringing in inverter and rectifier circuits are present in the extraneous magnetic field. We present two modifications to the internal circuitry which further improve the time-domain performance of the system to the extent that it approaches having a distortionless transfer function. Finally, we present a physical explanation for the mechanism by which the time-domain performance is improved.
Van Veen环的时域性能
范维恩环本质上很好地适应于净磁偶极矩的时域测量。也就是说,该系统非常接近于保留由DUT产生的净磁偶极矩或剩余磁偶极矩的时域波形的形状。这一特性使得范维恩环路在磁场无线电力传输系统的表征中非常有用,在这些系统中,诸如逆变器和整流电路中的振铃等短时间尺度特征存在于外部磁场中。我们对内部电路进行了两种修改,进一步提高了系统的时域性能,使其接近于具有无失真传递函数。最后,我们给出了时域性能改善机制的物理解释。
