LabVIEW modeling of frequency dependence of power losses in soft magnetic materials

The paper deal with Steinmetz power losses equation developed in LabVIEW program. The initial equation is used after the area of hysteresis cycle is calculated using the LabVIEW VI´s. It is important to have enough points considered on the major hysteresis loop to obtain with good accuracy the power losses. For this reason we use some VI´s to interpolate the space between measurement data to have more datas. In this paper we made only the frequency dependence of the power losses and in the future we plan to go to the time domain. We try also to made the power losses separation between hysteresis losses and other losses taking for the DC case the frequency f=0,05 corresponding to IEC 60404 which specifies that for one major cycle is enough to be obtained in 20 seconds.
