摘要

A model for estimating uncertainty in measurements of the mutual inductance and equivalent load resistance of an inductive power transfer system has been developed using a method for estimating these values based on the characteristics of the transmitting part of the system. Uncertainty is estimated using the Monte Carlo method for two scenarios: with high and low measurement uncertainty. For the selected system parameters, the maximum relative deviation of the mutual inductance in the range 20–25 μH for high uncertainty was by 10% for the upper limit and 5% for the lower limit. The maximum relative deviation of the load resistance in the range 5–10 Ω was by 74% for the upper limit and 61% for the lower limit. In the case of low uncertainty, the relative deviations of both quantities from the true value were by no more than 1%.
