Hey Yuan,

Please share your dead time settings with us, you may be causing shoot through to happen.

Can you share the phase current waveform?

We can go from there.

Thanks,

Michael

Hi Juan,

Did you have any luck getting the over current fault to go away? Is there anything else I can help you with?

Thanks,

Michael
