Abstract
Vindmøller er afhængige af højeffekt-omformere. I disse omformere er IGBT-moduler (effektelektroniske switche) ofte det svage led. Dette speciale beskriver analyse, design, implementering og validering af en power-cycling testopstilling, der fremskynder slid og muliggør levetidsundersøgelser af højeffekt IGBT-moduler. Opstillingen kan teste op til 10 PrimePACK 3-moduler med jævnstrøm op til 2000 A og giver stor fleksibilitet i driftsbetingelser. Styring af gatesignaler, dataopsamling og overvågning er udviklet i NI LabVIEW. Der er desuden implementeret to metoder til at estimere junction-temperaturen (chipens indre temperatur) ud fra databladparametre. Infineons PrimePACK 3-modul FF1000R17IE4 testes aktuelt, og resultaterne præsenteres i rapporten.
Wind turbines rely on high-power converters, where IGBT modules (power electronic switches) are common points of failure. This thesis presents the analysis, design, implementation, and validation of a power-cycling test setup that accelerates wear and supports lifetime studies of high-power IGBT modules. The setup can test up to 10 PrimePACK 3 modules with direct current up to 2000 A, allowing a wide range of operating conditions. Gate signal control, data acquisition, and monitoring were developed in NI LabVIEW. The work also implements two methods to estimate junction temperature (the chip’s internal temperature) using datasheet parameters. The Infineon PrimePACK 3 module FF1000R17IE4 is currently under test, and the results are reported.
