Abstract

This paper shows different state of the art analytical iron loss models and a modified model, which combines the modified Bertotti model with the form factor of Grätzer. A loss comparison under sinusoidal and non-sinusoidal voltage excitation in the frequency range from 50Hz to 1000Hz without minor loops is shown. Measurements show that the accuracy of some models is high, independent from the shape of the voltage and easy to apply for engineers designing inductive components in power electronic applications.
