EDUCATIONAL LABORATORY FOR THE STUDY OF POWER CONVERTER THROUGH A WEB BROWSER

摘要

The solution that is shown in this paper allows to students of different subject of Power Electronics, the accomplishment of a complete study of DC/DC converters, by means of two different exercises: 1. Design. The students must evaluate the behavior of the power circuit in open loop, choosing among different values of components for the implement of the studied topology. The software facilities tools for the measure of the main waveforms of the topology, such as: inductor current, control signal to the switch, output voltage... 2. Test. After the study of the power circuit, the software allows to analyze response of the power converter in close loop, by means of a set of test: line regulation, load regulation... The developed system is based on a test bench manufactured by Hewlett-Packard. Taking this one as starting point, a software application has been developed using the graphical programming language "LabVIEW". This programming tool combined with CGI (Common Gateway Interface), allows the remotely execution using a web browser, increases the versatility and utility of the system.
