Question
How to diagnose EV traction inverter gate driver faults?
Answer
It identifies failures in the circuit driving inverter power transistors.
Explain
Gate drivers control the switching of inverter IGBTs/MOSFETs. CHEPQ EV diagnostic tools monitor gate driver voltage, current, and fault signals, detect short circuits, open circuits, or thermal stress, and verify driver IC functionality. This prevents inverter damage, ensures smooth motor control, and avoids EV drivetrain failures.
