What you'll do:

1. IGBT Fault Diagnosis & Technical Support

• Conduct fault analysis and diagnostics for IGBT components used in UPS and power modules, identify failure mechanisms, and propose repair solutions.
• Utilize diagnostic tools such as double-pulse test platforms, infrared thermal imaging, and SEM (scanning electron microscopy) to locate faults and determine root causes.
• Analyze the interaction between IGBT failures and drive/protection circuits, supporting system-level troubleshooting.

• Handle IGBT fault cases in data center power modules, addressing issues such as thermal aging under high power density and insulation resistance degradation due to coolant contact.
• Provide recommendations on IGBT selection and performance evaluation tailored to data center requirements, including overload capability, EMC compliance, and low-temperature startup characteristics.

• Collaborate with UPS system teams to optimize protection logic and response mechanisms related to IGBT failures.
• Guide external vendors on repair processes (e.g., re-soldering temperature control, silicone gel insulation treatment) to ensure repaired modules meet data center reliability standards.

1. Technical Expertise

• Over 8 years of experience in IGBT R&D, testing, or fault diagnosis for UPS or power modules.
• Proficient in mainstream IGBT models (e.g., Infineon FF450R12ME4, onsemi NGB1200XX series), including electrical characteristics and failure mechanisms.
• Skilled in diagnostic tools and methods such as double-pulse testing, thermal imaging, and SEM analysis.

• Proven track record with 10+ IGBT fault cases in data center environments.
• Familiar with data center-specific IGBT requirements, including 150% overload for 15 minutes, EMC compliance, and operation in -5℃ to 40℃ conditions.

• Capable of producing fault analysis reports and communicating effectively with system teams.
• Able to instruct external vendors on repair techniques and ensure post-repair reliability.
