近10幾年來，隨著通訊事業之迅速發展，行動電話、個人數位助理等電子裝置越來越普及。該等電子裝置於組裝完成後，一般均需要對其中一些功能進行測試，以檢測電子裝置是否達到規定標準，此時測試用電源裝置的穩定性及相容性就顯得格為重要。 本篇論文中，我們提供一種測試用電源裝置，其用於為一待測電子裝置提供測試所需之電源，所述測試用電源裝置內設置有一切換電路，切換電路包括第一輸出端、第二輸出端及第三輸出端，所述第一輸出端、第二輸出端及第三輸出端分別與所述待測電子裝置之正連接器端子、ID連接器端子及負連接器端子一一對應，所述第二輸出端於切換電路之控制下可分別輸出兩種不同內阻電壓，其分別用於測試所述待測電子裝置中工作於習知電池提供之常規電壓之元件及工作於習知電池無法輸出之特殊電壓之元件，並對無線電頻率測試進行模擬驗證。 Over the Past 10 Years, With the Rapid Development of Telecommunications Industry, Mobile Phone, Personal Digital Assistant and Other Electronic Products is Becoming Increasingly Popular. Those Electronic Products are Kind of Electronic Devices. While The Electronic Devices in the Assembly is Completed, Generally Need to Test Some of Functions to Detect Whether Approach Standards or not. Testing the Stability and Compatibility for The Point Power Supply Unit Becomes Very Important. The Purpose of This Paper, It Provide a Dummy Battery Apparatus, Which Used an Electronic Device Under Test Required for Testing Power Supply. The Dummy Battery Apparatus Has a Switch Circuit, Switch Circuit Including The First Output, The Second Output and The Third Output. The First Output, The Second Output and The Third Output is Corresponding to a Positive Connector Terminal, an ID Connector Terminal and Negative Connector Terminal of the Untested Electronic Device. Under the Control of the Switch Circuit, Two Different Voltages can be supplied by The Second Output. One of the Voltages Can be Used to Testing Some Components Which works Under a Conventional Battery Voltage, The Other one can be Used to Testing Some Components which Works Under a Specific Voltage, and simulation and verification for radio frequency test.
