高频下直流偏置对磁芯损耗影响的研究与建模

This article aims to study the core losses behavior at high frequency (MHz range) with superimposed dc bias in ferrite. Inductive compensation method is employed in the measurement circuit to reduce sensitivity to phase errors. An addition to the circuit is proposed in this work to make easier dc bias generation. Furthermore, a detailed measurement accuracy consideration is also discussed. The tes...
