摘要：在電力電子技術的早期，使用壽命的評估僅限于最大負載條件和寬松的裕量。今天，通過對反映負載和冷卻系統動態特性的專用任務配置進行評估，來估計電力電子系統的使用壽命。這種方法提高了預測質量，但它需要更好且更精細的使用壽命模型。本文將介紹如何推導先進功率模塊的使用壽命模型。 敘詞：先進功率模塊 SKiM63 使用壽命模型 Abstract：In the early stage of power electronics technology, evaluation of service life was limited to the condition of maximum load and ample margin. Today, it is evaluated through dedicated-task configuration reflecting load and dynamic performance of cooling system, which improves the quality of prediction. However, such a method needs a better and finer service life model. This paper will tell how to deduce the service life model of advanced power module.
