要約(英語): Because of the improved performance of power devices, the volume of the AC filter inductors used in the high-frequency PWM inverters has reduced. However, the temperature rise in the filter inductor due to the miniaturization has become more pronounced. Therefore, the authors have proposed the iron loss calculation method for the AC filter inductor. However, the accuracy of the value calculated via the loss map method cannot be verified, because the iron loss arising during each switching duration cannot be measured using the conventional power measuring instruments. In order to solve this problem, we developed an inductor loss analyzer (ILA), which enables the measurement of the iron loss of the inductor precisely during each switching period. The accuracy of the iron loss of the filter inductor calculated by the loss map method is verified using the ILA. It is found that the value calculated via the loss map method differs slightly from the value measured using the ILA. However, these differences can be reduced if we take into the accurate flux density calculation and the loss effect of the duty ratio of the PWM pulse. Finally, it is verified that the loss map method can provide accurate iron loss calculation.
