一般来说,在我们认知的过程中,社会和科学技术的进步已经开始引导着人们的生活,有关生活方面的问题开始逐渐展现在人们的眼前。有关开关线路电源已经逐渐应用到人们的生活中,与我们的日常生活息息相关。在一定程度上,我们对于开关电源的可靠性要求也在不断的提高,所以一旦涉及开关电源的电气控制回路问题是值得我们关注的,也是我们将重点解决的问题。 Generally speaking, in the process of our cognition, the progress of society and science and technology has begun to guide people’s lives. The problems concerning life are gradually beginning to show to the people. Switching power supply has been gradually applied to people’s lives, and our daily life are closely related. To a certain extent, we are also constantly increasing the reliability requirements of switching power supplies, so once the electrical control loop involving switching power supplies is worth our attention, it is also a problem that we will focus on.
