为了评估逆变电路中功率半导体特性对磁性材料磁性能的影响，我们提出并测试了一种新的数值计算方法。该方法将功率半导体电流电压特性的电路分析与基于磁滞模型的磁分析相结合。先前对逆变器的测量表明，功率半导体的on电压会影响其磁性能，如B-H曲线（B为磁通密度，H为磁场强度）和铁损耗。这些测量激发了本文的写作动机。本文采用的磁滞模型是一种基于物理热力学理论的新颖方法，能够捕捉物理磁现象的本质。用该方法进行的计算表明，B-H曲线中测量到的小回路得到了很好的表示，计算得到的电压波形能很好地捕捉到导通电压效应。
To evaluate how magnetic properties of magnetic materials are influenced by power semiconductor properties in an inverter circuit, we propose and test a new numerical calculation method. This method combines an electrical circuit analysis for current-voltage properties of power semiconductors with a magnetic analysis based on a magnetic hysteresis model. Previous measurements on an inverter show that magnetic properties, such as B-H curves (B is the magnetic flux density and H is the magnetic field intensity) and iron losses, are affected by ON-voltages of power semiconductors. Those measurements motivate this paper. The magnetic hysteresis model used here is a novel approach that is based on physical thermodynamics theory and can capture the essence of physical magnetic phenomena. Calculations with the proposed method show that measured minor loops in B-H curves are well represented and calculated voltage waveforms properly capture ON-voltage effects.
