摘要

近年來，由於3C (Communications, Computer, Consumer-electronics)產品日趨小型化。因此，用以供電3C產品之電源供應器所需之電力電子技術日益重要，以因應電源供應器小型化所衍生出之電磁干擾與散熱的問題。為了確保電源供應器之品質與可靠度，於其出廠前必須先行測試。傳統之測試方式大多採用電阻作為其測試負載。因此，當測試時間越長或測試數量越多時，測試所損耗的能量就越大，所花費的金額也就越高。有鑑於此，本論文提出一具多組主動式負載之數位化燒機測試(Burn-in Test)平台，將電源供應器燒機時所需之能量回送至輸入端以降低所損耗之能量，並利用數位控制方式達到監控之目的。最後以實驗結果驗證此數位化燒機測試平台之可行性。

Recently, the 3C (Communications, Computer, Consumer-electronics) product is getting smaller and smaller. However, the power supply used to feed the 3C product is indispensable for size reduction. Consequently, the technology of power electronics is getting more and more important so as to reduce the effect of the resulting heat and EMI (Electromagnetic Interference) created from the power supply on itself and the 3C product.
Accordingly, the operation reliability of the power supply is a vital concern that needs to be qualified in a prudent manner before use of the power supply. The burn-in test is recognized as a feasible approach to certification of the quality of the power supply, and yet with the resistor used as a testing load traditionally, it results in unwanted energy consumption that inadvertently causes an increase in cost.
Based on the mention above, a digital burn-in test plant with multiple active loads is proposed herein, which can recycle energy during the period of the burn-in test. Besides, the associated currents and voltages are monitored. Some experimental results are provided to demonstrate of the effectiveness of the proposed scheme.
