开关电源由于其功耗小、效率高、体积小、重量轻、稳压范围宽等优点,彩色电视机基本上都采用开关式稳压电源。但同时某种程度上增加了维修者的难度;也是彩电中最易损坏的单元电路之一。有些维修人员因没有完全掌握其特点,检修中常发生危及人员和设备安全以及人为扩大故障的现象。为此本文谈谈检修开关电源时应注意的问题,希望能对彩电维修人员小有帮助。
Switching power supply due to its low power consumption, high efficiency, small size, light weight, wide voltage range, color TV basically switching power supply. But at the same time to some extent, increased the difficulty of maintenance; color TV is one of the most vulnerable unit circuit. Some maintenance staff because they do not fully grasp its characteristics, maintenance and endangering the safety of personnel and equipment, as well as man-made to expand the phenomenon of failure. To this end, this article talked about the maintenance of switching power supply should pay attention to the problem, hoping to help small color TV repair personnel.
