If you desire to be part of something special, to be part of a winning team, to be part of a fun team – winning is fun. We are looking forward to a IGBT Fault Diagnosis & Repair expert in Eaton’s electrical business, based in Shenzhen, China. In Eaton, making our work exciting, engaging, meaningful; ensuring safety, health, wellness; and being a model of inclusion & diversity are already embedded in who we are - it’s in our values, part of our vision, and our clearly defined aspirational goals.
What you’ll do:
- 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.
- Data Center Scenario Adaptation
- 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.
- Cross-Team Collaboration & Repair Implementation
- 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.
Qualifications:
- 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.
- Data Center Application Experience
- 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.
- Communication & Collaboration Skills
- 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.
Yes! Because you are the one we are looking for, we hope to hear from you now!
