二、开关电源输出电压升高的故障徒弟:据我所知,在开关电源电路故障中,因稳压反馈控制环路出问题而引起电源输出电压升高,并造成元件烧损或保护电路动作而开启难、自动关机等多种故障屡见不鲜。请师傅举典型的故障例子,讲解检修思路与技法好吗? 师傅:好的,你说的不错,这种输出电压升高的故障的确常见,并对整机其他电路的危害性也很大。由于故障及原因多种多样,因此,需要掌握故障规律和检修思路以及检修技法等显得很重要,现举例分析检修如下:
Second, the switching power supply output voltage fault apprentice: As far as I know, in the switching power supply circuit failure, due to regulator feedback control loop problems caused by the power supply output voltage increases, and cause component burnout or protection circuit action And difficult to open, automatic shutdown and other failures are commonplace. Master please give typical example of failure to explain maintenance ideas and techniques alright? Master: Well, you said good, this output voltage is indeed a common failure, and the dangers of the other circuit is also great. Due to a variety of faults and causes, therefore, it is important to know the rules of the fault, the ideas of overhauling, and the overhauling techniques. The examples are as follows:
