摘   要
 
 開(kāi)關(guān)電源具有許多良好特性,應(yīng)用非常廣泛。開(kāi)關(guān)電源在設(shè)計(jì)、研發(fā),調(diào)試及驗(yàn)收過(guò)程中,需要測(cè)試許多性能和技術(shù)指標(biāo)。通常我們可以將這些測(cè)試分為功能測(cè)試、保護(hù)性能測(cè)試、安全性能測(cè)試、電磁兼容測(cè)試、可靠性測(cè)試以及其它特殊的附加測(cè)試等六大部分。本文主要介紹了常規(guī)功能的測(cè)試，選取了測(cè)試項(xiàng)目為線性調(diào)整率測(cè)試、輸出負(fù)載調(diào)整率測(cè)試、效率測(cè)試、輸出紋波電壓及噪音測(cè)試、輸出過(guò)流保護(hù)功能測(cè)試。兩種方法：一種為基于儀器的手動(dòng)測(cè)試，文中詳細(xì)介紹了部分測(cè)試項(xiàng)目的定義以及具體的操作方法，參考數(shù)據(jù)記錄表格的提供等，手動(dòng)測(cè)試具有測(cè)試靈活，數(shù)據(jù)準(zhǔn)確等特點(diǎn)，但測(cè)試耗時(shí)，過(guò)程繁瑣，效率不高。此文，鑒于手動(dòng)測(cè)試的繁瑣性等缺點(diǎn)，文中特別嘗試了搭建基于LabVIEW 的自動(dòng)測(cè)試系統(tǒng)，介紹了平臺(tái)搭建的幾個(gè)關(guān)鍵技術(shù)點(diǎn)，自動(dòng)測(cè)試具有效率高，測(cè)試速度快等特點(diǎn)。最后并將手動(dòng)測(cè)試和自動(dòng)測(cè)試系統(tǒng)測(cè)試所得的數(shù)據(jù)進(jìn)行了比較，結(jié)果證明了測(cè)試系統(tǒng)的可行性。

Abstract
 
Switching Power Supply has many good features, a wide range of applications. Switching power supply in the process of design, development, testing and approved, it need to test a number of performance and technical indicators. Usually we can divide these tests into functional tests, the protection performance testing, security testing, electromagnetic compatibility testing, reliability testing, and other additional tests. This paper introduces the features of conventional tests, test items selected for the linear adjustment of the rate of testing, the output load regulation test, efficiency test, the output ripple voltage and noise testing, output over-current protection function test. Two methods: a manual based on the test apparatus, described in detail the definition of some of the test items as well as specific methods of operation, the provision of data records such as forms, manual test with a test flexible, accurate data, but test time-consuming, cumbersome process, efficiency is not high。This article, in view of the cumbersome manual testing of such shortcomings, in the text has been set up specifically to try base LabVIEW to build automated test system and introduce several key technologies about to build automated test. The automated test with a high efficiency, speed tests and so on. Finally, manual and automatic test system to test and test data, the results prove the feasibility of testing the system.
