摘要
通过实测ARROW750立式加工中心电源板的开关电源电路,分析各部分的工作原理,对关键的DC-DC变换器及CA3524E控制电路进行了深入研究,并结合故障现象的分析判断检测出故障点,进而修复开关电源。
Basing on testing the switching power supply circuit of ARROW750 vertical machining center power panel, the principles of the parts are analysed. The key DC-DC converter and CA3524E control circuit are researched in-depth,and combines with the analysis judgment of the breakdown phenomenon to examine the fault point and repair switching power supply.
