BESS equipment presents serious hazards and must only be serviced by properly trained, qualified, and authorized personnel in accordance with applicable codes, standards, OEM requirements, and site procedures.
Course Overview
IGBTs (Insulated Gate Bipolar Transistors) are primarily used in the Power Conversion System (PCS) within the Battery Energy Storage System (BESS). IGBTs play a critical role in enabling efficient, bidirectional energy conversion, transforming direct current (DC) from batteries into Alternating Current (AC) for grid use and vice versa.
Common Failure Scenarios Requiring Testing
Quick, accurate troubleshooting restores system operation safely and minimizes downtime.
- Follow proper safety procedures before IGBT testing
- Perform visual inspections to identify failed components
- Test IGBT modules in-system and on the bench
- Test individual IGBT components and associated parts
- Interpret test results to determine component status
