Summary:Medium frequency transformers are an essential part of new energy conversion systems, and are very often subject to non-sinusoidal excitation. Therefore, usual methods to represent magnetic materials behavior inside transformers with electrical equivalent scheme are very limited in this case. This paper focuses on the development of a new model based on the loss separation method. This model is implemented in a circuit simulation software with the VHDL-AMS modeling language to represent the behavior of a flux tube: non-linearity, hysteresis and losses. It allows to obtain relevant results for any excitation waveform as the model is temporal. The developed model was compared with experimental results on a small-scale nanocrystalline transformer prototype and it remains very accurate regarding the hysteresis cycle shape and core losses over a wide frequency range, and also for different waveforms.
