This paper describes a model for simulating the behavior of soft MnZn. This model takes into account both hysteresis and dynamic phenomena. The temperature is introduced using behavioral laws. In fact, the following model requires only few parameters. It estimates iron losses and characteristics, such as B(H), φ(t), and the induced electromotive force. The obtained results are compared with measured data for three soft MnZn ferrites currently used in power electronics. The comparison found good agreement in a wide range of operating frequencies for temperatures ranging from 40 to 140°C
