下面上传个电路图，里面的PNP的光敏三极管找不到，可以用3DU33代替，是NPN的，注意电流方向就行了，带凸脚的一边是发射极，我是准备拿来做光源追踪，再准确点就是日光追踪今天发现一个问题，两只光敏三极...

400V8A60W的管子呀~好像电压是7.5v的电压吧~用12V的电源好像勉强了一点吧~你是好像是用电蚊拍的单管自激电路吧！提高效率用双管推挽式的~如果是用高压包做的，就把那根夹磁芯的弹簧钢去掉。我原...

1、9013接错，E-B反压只有5~6V耳，不论是开关打在“U”还是“I”档，击穿烧毁没商量。2、电压取样点在3DD15基极，输出电流变化导致的输出电压变化可以达到0.2V以上。3、没有过压保护措施，...
