Description

201024769 六、發明說明: 【發明所屬之技術領域】 本發明係關於一種電源供應裝置,特別關於一種應用 於測試設備中之以電子式開關切換的電源供應裝置。 【先前技術】 電子產品在半成品階段或成品階段皆須要經過測 試,確認功能正常後,才能夠送往下一個製程或出貨。而 要確認產品功能是否正常,通常必須由測試設備提供一個 • 電源使電子產品作動後,才能進行檢測。 ' 習知的測試設備中,在待測裝置與電源之間通常會使 用一機械式開關,以控制電源是否傳輸至待測裝置。所謂 的機械式開關是利用機械動作而作導通或截止的切換,例 如按鈕開關、指撥開關、無熔絲開關或磁簧開關等,皆是 靠機械式的動作而將電源導通或截止。 然而,在機械動作的過程中常會造成設備抖動,且在 Φ 導通的瞬間容易產生高壓脈衝。高壓脈衝相當於是瞬間提 供了一個比正常能量更大的能量至待測裝置,因此當此能 量大於待測裝置的負荷時,則容易損壞待測裝置。另外, 機械式開關通常必須藉由人力操作,因此將難以使得測試 的過程自動化以提升效率。 因此,如何提供一種能夠抑制測試設備中由機械式開 關所造成的高壓脈衝,且能夠使得測試過程自動化的電源 供應裝置,實屬當前重要課題之一。201024769 VI. Description of the Invention: [Technical Field] The present invention relates to a power supply device, and more particularly to a power supply device for electronic switch switching applied in a test device. [Prior Art] Electronic products must be tested in the semi-finished or finished product stage to confirm that they are functioning properly before they can be sent to the next process or shipped. To confirm that the product is functioning properly, it is usually necessary to provide a power supply from the test equipment before the electronic product can be activated. In conventional test equipment, a mechanical switch is usually used between the device under test and the power supply to control whether the power is transmitted to the device under test. The so-called mechanical switch is a switch that is turned on or off by a mechanical action, such as a push button switch, a dip switch, a no-fuse switch, or a reed switch, etc., all of which are powered on or off by mechanical action. However, equipment shakes are often caused during mechanical motion, and high voltage pulses are easily generated at the moment of Φ conduction. The high voltage pulse is equivalent to instantaneously providing a larger energy than the normal energy to the device under test, so when the energy is greater than the load of the device under test, the device to be tested is easily damaged. In addition, mechanical switches typically have to be operated manually, so it will be difficult to automate the testing process to increase efficiency. Therefore, it is one of the current important topics to provide a power supply device capable of suppressing high voltage pulses caused by mechanical switches in a test device and capable of automating the test process.
