摘要：
In order to improve the calculation accuracy of core loss in power electronic devices under complex excitation, two core loss calculation methods under rectangular waveform with DC bias excitation (non-sinusoidal excitation for short) were proposed in this paper. Firstly, the Rectangular Extension of Steinmetz Equation (RESE) was modified, and the corresponding expressions were derived. Secondly, considering the nonlinearity of equivalent conductivity ρ under non-sinusoidal excitation, the core loss separation method was further modified. Then, based on the hysteresis loop measurement system, the core loss of Hitachi nanocrystalline core (FT-3KS) under sinusoidal and non-sinusoidal excitations was measured in the range of 20kHz. By fitting the curves of the core loss, the analytical expressions of the above two methods were acquired. Finally, the above methods were verified by the comparison between the measured values and the model predictions. The average prediction error of the two methods is controlled within 10%. © 2022, Electrical Technology Press Co. Ltd. All right reserved.
