摘　　要：参照机械开关的伏安特性曲线,建立了电力二极管、晶体管、场效应管等半导体开关器件的伏安特性曲线,可明确理解各自"通态"和"断态"以及状态之间转换的意义.对半导体开关相关教学内容的重新组合,也有利于在学时较少的情况下准确理解这些半导体开关器件的主要参数.Referring to the V-A characteristic curve of the mechanical switches, the simplified V-A characteristic curve of some semiconductors, such as the power diodes, transistors, MOSFETs, was established. In this way, the meanings of the ＂ON＂ and ＂OFF＂ states, as well as the transient conditions of these semiconductors were clear and easy for understanding. The re-arrangement of the contents related to semiconductor switches was also helpful for the accurate understanding of the main parameters of these semiconductor switching devices in less teaching hours.
