Automated Test Bench (ATB)

A large number of power converters are required to energize various electromagnets in particle accelerators. It therefore becomes imperative to carry out thorough testing of these power converters before they are deployed in the system to ensure intended functionality and overcome the infant mortality. Of late, various type tests, test sequences and test parameters have been conceived to evaluate a power converter performance. Earlier, they were executed mostly manually with the help of remote interface module. Automation is required to facilitate conducting routine test on magnet power converters in an orderly, streamlined and more efficient manner with proper documentation of the test results. Therefore, an Automated Test Bench (ATB) is developed to facilitate automated testing of power converters. It consists of a control interface module (CIM), DCCT racks, oscilloscope, data logger, master patch panel and a computer.
