Question
What diagnostic methods apply to EV DC-DC converter output ripple faults?
Answer
It identifies excessive ripple affecting low-voltage system stability.
Explain
DC-DC converters convert high voltage to low voltage (12V). CHEPQ oscilloscopes measure output ripple amplitude and frequency, detect capacitor degradation, inductor faults, or switching transistor issues, and verify converter regulation. This prevents low-voltage system malfunctions, such as ECU resets or sensor errors.
