Research on Test Methods and Platform Design for IGBT Power Components

This paper addresses the testing requirements for high-power IGBT power components and proposes a safe, energy-efficient, highly versatile, and compatible method for reactive current power cycle test for various power components.The designed testing platform is compatible with two-level and three-level topologies, integrates power cycle testing and intelligent fault diagnosis functions, It is capable of conducting a complete test on the power components independently of the entire converter/inverter unit. The platform gradually detects faults through preset programs, combines test data with fault libraries for analysis, and effectively improves the testing efficiency and fault diagnosis accuracy of power components.
