自耦变压器是常用的变压器之一 ,在中学物理教材中只作了粗浅的介绍 .为对自耦变压器及其应用有更进一步的认识 ,本文作些适当的补充 ,供大家参考 .一、自耦变压器的结构特点图 1是自耦变压器的示意图 .这种变压器的结构特点是铁芯上只绕有一个线圈 .如果把整个线圈作原线圈 , Autotransformer is one of the commonly used transformers, and only a brief introduction is given in the middle school physics textbooks. For a better understanding of the autotransformer and its applications, this article makes some appropriate additions for your reference. The structural characteristics of the coupling transformer Figure 1 is a schematic diagram of an autotransformer. The structural characteristics of this transformer is that there is only one coil around the core. If the whole coil is used as the original coil,
