Inhalt:
Power cycling tests with online junction temperature measurement are well established for IGBTs, MOSFETs and diodes, standards applied in industry and at research facilities are currently emerging. However, for thyristors, recent intense power cycling reliability studies are unknown. In this work, an application-close test method with alternating load current and online temperature measurement based on two temperature sensitive-parameter using VGC (TJ) and VAC (TJ) for thyristor power modules is introduced. First test results of power cycling tests with direct and alternating load current are presented.
