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 ...
