Abstract
Based on coupled field-circuit model
the magnetic field and inductance of air-core reactor are computed by using finite element software. The distribution of magnetic field and the current of the winding of one type of air-core reactor are presented. The comparison of calculated values with measured values shows that the proposed method has high accuracy.
