摘要

为了预测任意激励下的磁芯损耗，将与磁通密度的摆幅和直流偏置有关的准静态能量损耗乘以有效频率。有或没有直流偏置的各种形状的磁通密度(例如正弦和三角形波形)的测量结果验证了该紧凑模型。

Compact Core Loss Model Based on an Effective Frequency for Arbitrary Core Excitations Including DC-Bias

To predict core losses for arbitrary excitations, the quasi-static energy losses depending on the swing and the DC-bias of the magnetic flux density are multiplied by an effective frequency. Measurement results for various shapes of the magnetic flux density (e.g. sinusoidal and triangular waveforms) with and without DC-bias verify this compact model.
