摘　　要：电源模块作为电子设备的心脏,其工作性能和使用寿命直接决定了电子设备的可靠性,通过对电源模块内部器件进行分析,找出影响其寿命的薄弱器件为电解电容,结合Icepak热仿真确定该器件工作温度,计算出其使用寿命,进而估算电源模块的寿命。Power module as the heart of the electronic equipment,its working performance and service life directly determine the reliability of the electronic equipment,by analyzing the internal components of the power module,found that the weak component that affects its service life is electrolytic capacitor,combined with the thermal simulation results to find the working temperature and to calculate the service life of the component,then the service life of the power module is estimated.
