电器已经成为我们生活中不可获取的物品,任何电子产品都需要电源对其提供电能,从而保证其具备基本动力。其中,开关电源是20世纪70年代左右新兴的电源结构,不仅具有重量轻和体积小的特点,且整体设备的功耗小,效率却较高,能保证整个电子设备的稳定性和可靠性,一定程度上实现了广泛推广。本文对开关电源设计原理进行了简要分析,并对其常见故障展开了讨论,旨在为设备管理人员提供有价值的参考建议。 Electrical appliances have become an item not available in our lives, and any electronic product requires power to power it, thus ensuring that it has the basic power. Among them, the switching power supply is a new power structure around the 1970s, not only has the characteristics of light weight and small size, and the overall power consumption of small devices, but higher efficiency, to ensure the stability and reliability of the entire electronic equipment, To a certain extent, achieved wide promotion. This text has carried on the brief analysis to the switching power supply design principle, and has carried on the discussion to its common breakdown, aimed at the equipment management personnel to provide the valuable reference suggestion.
