Abstract
Thepaper conducts statistical analysis on the damaged power modules of a certain power supply bureau from 2012 to 2019,obtains relevant data,and summarizes the characteristics of the damage patterns.It introduces the working principle of the power module and conducts in-depth analysis from the aspects of electronic component quality,on-site operating environment and temperature,operating time limit,DC power quality,and overvoltage.It concludes that the main reasons for module damage are poor manufacturing quality of electronic components,high operating environment temperature,long operating time limit,large DC power ripple current,and overvoltage.Corresponding operation and maintenance measures are proposed based on the analysis conclusions.关键词
