开关电源具有体积小、重量轻、效率高等诸多优点，凭借其自身的诸多优势，开关电源已经广泛应用于航空航天、通信、以及电子类。由于应用领域的广泛性，开关电源的可靠性引起了人们的重视。论文以阿伦尼斯（Arrhenius）模型为基础，设计了一整套针对开关电源的可靠性评价和寿命预计的试验方案。该方案对试验器件施加温度应力，加速器件的失效过程，并通过一定的加速模型和统计分析方法，外推出正常工作条件下产品的寿命特征。
開關電源具有體積小、重量輕、效率高等諸多優點，憑藉其自身的諸多優勢，開關電源已經廣汎應用于航空航天、通信、以及電子類。由于應用領域的廣汎性，開關電源的可靠性引起瞭人們的重視。論文以阿倫尼斯（Arrhenius）模型為基礎，設計瞭一整套針對開關電源的可靠性評價和壽命預計的試驗方案。該方案對試驗器件施加溫度應力，加速器件的失效過程，併通過一定的加速模型和統計分析方法，外推齣正常工作條件下產品的壽命特徵。
