摘要

开关电源的功能和诊断测试提供了独特的挑战。控制回路和普遍存在的破坏性和雪崩失效模式使许多故障的分析和诊断变得困难。传统的休息方法被应用于电源,但被证明是不够的。本文通过实例说明了在此过程中遇到的一些问题及其解决方法。本文还将讨论车厂级电源测试仪,即高级电源测试仪(APST)的定义过程。该测试仪具有由LabWindows CVI和FineSoft提供的软件环境和图形用户界面(GUT),硬件由实验室质量仪器和诊断工具组成。

Test strategies for power supplies
Functional and diagnostic testing of switching power supplies offers unique challenges. The control loop and the prevalence of destructive and avalanche failure modes make it difficult to analyze and diagnose many failures. Traditional approaches to resting were applied to power supplies and proved inadequate. This paper illustrates, through examples, some of the problems encountered and their solutions. This paper will also discuss the process through which a depot level power supply tester, the Advanced Power Supply Tester (APST), was defined. The tester features a software environment and Graphical User Interface (GUT) provided by LabWindows CVI and FineSoft, hardware consisting of an assembly of laboratory quality instrumentation, and diagnostic tools.<>
