思考题:试用W317构成一个0～25V连续可调的稳压器。 上期思考题答案:有两种方法:一是调整耦合回路初、次级电感线圈的同名端;二是颠倒检波二极管的方向。 编者后记 按计划,模拟电路实用知识讲座到本讲为止结束。我们要感谢李金平老师为办好这一讲座付出辛勤的劳动,也感谢广大读者对这一讲座的关心和支持。 Questions: Try W317 to form a 0 ~ 25V continuously adjustable voltage regulator. Answer to the previous question: There are two ways: First, adjust the coupling loop primary and secondary inductance coil end of the same name; the second is the direction of the detector diode upside down. Editor’s Postscript According to plan, practical knowledge of analog circuits lectures to the end. We would like to thank Professor Li Jinping for his hard work in running this lecture and for the readers’ concern and support for this lecture.
