TEMPERATURE DEPENDENCE OF EDDY CURRENT LOSS AND RESIDUAL LOSS IN Mn-Zn FERRITES

Abstract

In this paper, the temperature dependence of eddy current loss and residual loss is investigated with relationship between (PB-Ph) and electrical resistivity at the temperature region except T min \vhich hysteresis loss attains minimum. Consequently ,a quantitative separation of each loss has been made possible not only at T min but at any temparature. Pe increases with increasing temperature. The temperature dependence of the eddy current can be concluded to be caused by the change in the electrical resistivity with temperature.
