Abstract—An accurate and fast transient calorimetric
ferrite core-loss measurement method is proposed in
this paper. In contrast to electrical measurements, the
accuracy of the calorimetric approach is independent
of the magnetic excitation and operating frequency.
However, an accurate value of the thermal capacitance
of the Core Under Test (CUT) is required, which can be
achieved, e.g., by measuring the specific heat capacity
of the measured core material using a Differential
Scanning Calorimeter (DSC) or by using the CUT as a DC
electric conductor and measuring its thermal response
for known Joule heating. The proposed method is tested
experimentally and compared successfully to a state-ofthe-
art electrical loss measurement method on MnZn
ferrite cores.
