Research and Implementation of Automatic Test Technology for Power Modules in Aerospace

摘要

The increasing variety and quantity of power modules for aerospace causes difficulty and complication for their testing. This paper studies the testing technology, develop the testing software and design with hardware universal interface to realize an automatic testing technology with data collection and interpretation, waveform automatic storage, command automatic switch, output channel automatic switch. The technology not only increases the testing efficacy by more than 100%, but also the risk factors caused by manual operation during the test are eliminated and the reliability and safety of the test system are improved. The technology is suitable for testing all current power modules.
