提出了一种基于正弦励磁铁芯损耗数据的电力电子变换器励磁铁芯损耗计算方法。该方法基于Brockmeyer理论，适用于直流偏置励磁条件下铁芯损耗的计算。此外，由于该方法只需要在铁芯制造商提供的正弦励磁铁芯损耗数据上添加直流偏置特性，因此减少了铁芯损耗测试条件的数量。为了验证所提出的方法，首先用带直流偏压激励单元的BH分析仪测量了正弦和平方电压激励下的铁芯损耗。然后，将方形电压激励下的实测值与正弦激励下铁芯损耗数据的计算值进行比较。
The authors propose a core loss calculation method for power electronics converter excitation from sinusoidal excited core loss data. This method is based on Brockmeyer’s theory and adapts to calculate core loss under DC-bias excitation conditions. Furthermore, the number of core loss test conditions are reduced as this method only requires the addition of DC-bias characteristics to the sinusoidal excitation core loss data provided by the core manufacturers. To validate the proposed method, the core losses under sinusoidal and square voltage excitations are first measured by a BH analyzer with a DC-bias excitation unit. Then, the measured values under a square voltage excitation and the calculated values from a sinusoidal excited core loss data are compared.
