Loss Calculation of Reactor Under Inverter Power Supply Taking into Account Anomalous Eddy Current Loss in Laminated Core

抄録

The iron loss of a reactor under an inverter power supply was calculated using the finite element method taking into account eddy current in the steel plate of laminated core. However, the calculated iron loss is much smaller than measured data due to neglect of the anomalous eddy current loss in the laminated plate.In this paper, a method of modifying the conductivity of steel plates for considering the anomalous eddy current loss is investigated. Moreover, the method is applied to the loss calculation of reactor under inverter power supply.
