关于互感元件教学的三个问题

Three Issues about the Mutual Inductor Teaching in Circuit Course

本文阐述了"电路"课程互感元件教学中的三个问题:消去互感前后磁链的变化;含有漏感和理想变压器的电路模型;工程上具有特殊工作条件的互感电路模型。在阐述这些问题时,运用了电磁学原理,衔接前后知识,联系工程案例,呼应后续课程。

This paper described three issues in the Circuit course teaching： the variations of magnetic flux before and after mutual inductance eliminated; the circuit models of coupling inductor which contains the leakage inductance and ideal transformer; the circuit models of coupling inductor working at the special conditions. In the introduction of these issues, the principles of electromagnetism are used, pre order and subsequent knowledge is joined, the engineering cases are demonstrated, and the follow-up courses are echoed.
