铝电解电容器广泛应用于各种电力电子电路和系统中。它的功能包括总线电压稳定、开关事件引起的涟漪电流传导等。在汽车应用中，最大的问题之一是它们必须承受的极端和恶劣温度，在夏季的几个月里，这些温度会降低它们的寿命。大多数电容器的最大额定温度为85或105“C，少数电容器的额定温度为125“C。根据文献发现，电解电容器中的主要磨损机制之一主要是由于电解质通过密封件的蒸汽扩散而损失。其他报告表明，主要的磨损机制是电解质的劣化。迄今为止进行的实验和相同的结果进行比较，对建模结果的基础上，最近的模型在文献中报道。
The aluminum electrolytic capacitor is widely used in various power electronic circuits and systems. Its functions include, bus voltage stabilization, conduction of ripple current due to switching events, etc. In automotive applications, one of the big issues is the extreme and harsh temperatures they have to withstand, underhood, which during the summer months would reduce their life. Most of the capacitors have maximum temperature ratings of either 85 or 105 "C and a few are rated at 125 "C. According to literature found, one of the primary wear-out mechanisms in electrolytic capacitors is mainly due to the loss of electrolyte by vapor diffusion through the seals. Other reports suggest that the main wearout mechanism is deterioration of the electrolyte. Experiments conducted to date and the results from the same are compared against modeling results based on a recent model reported in literature.
