如图和图5，对于感性负载，必须在负载两端并一个反向的续流二极管；三极管在关断时，线圈会自感产生很高的反向电动势，而续流二极管提供的续流通路，同时钳位反向电动势。防止击穿三极管； ...

两个NPN三极管搭建的直流降压稳压电源（至于为什么能够稳压，可以参照我前面发的文章《 这两个三极管是怎么做到恒流的？一起来分析一下 》 ） 输入电压DC24V，经过三极管Q1本身承受一定的压降后，输出电压Vo。

再来C9013，它是一个NPN型三极管。它分为三个极，分别是基极(b)、集电极(c)、发射极(e)，当对基极(b)施加高电平(大于0.7V)，基极(b)、发射极(e)导通，继而集电极(c)、发射极(e)导通；当对基极(b)低电平时(0V)，集电极(c)、发射极(e)之间截止。 进入正题，凝神聚力 ...
