摘要

PROBLEM TO BE SOLVED: To accurately estimate a true magnetic loss.An impedance real part calculation unit 132 obtains real part data (Z real ) from complex impedance data obtained from an impedance measuring device 14 capable of measuring a complex impedance in a primary coil (excited coil) of a toroidal core sample. .. Further, the AC coil resistance calculation unit 130 obtains the electric resistance (R 1_coil ) of the primary coil by calculation or simulation. Further, the magnetic loss calculation unit 136 acquires the magnetic loss (P core ) and the exciting current (I 1) when the magnetic loss is measured. Then, the magnetic loss calculation unit 136 applies the exciting current (I 1 ) to the value R 2_0 (= Z real −R 1_coil) obtained by subtracting the electric resistance (R 1_coil) of the primary coil from the real part data (Z real). the value obtained by multiplying the square of), by subtracting from the magnetic loss P core, estimate the true magnetic loss (P core ').
