Abstract :
Accurate measurement of core loss of low loss magnetic materials in the milliwatts range for high frequency applications is difficult to achieve due to its sensitivity to measurement error especially when measured at high frequencies. Magnitude and phase errors from the oscilloscope, probes/cables, current viewing resistors, phase shift between voltage and current, and noise coupling into measurement probes, which affect the measurement accuracies will be analyzed in detail.
