The system is suitable for continuous power testing of IGBT power modules of various sizes. Based on practical application environments, burn-in parameter test is built perform electrical stress burn-in test on the system. Simulate the working conditions of IGBT power modules in the use ofthe entire vehicle for long-term high current burn-in and motor stall testing. Real time monitoring of peak current, average current, input voltage, output voltage and temperature of the tested deviceduring burn-in process, record burn-in test data as needed, and export test reports
