BOOSTXL-DRV8305EVM: wave form of phase current and shunt current

Dear all,

Could you teach about the wave form at attached file?

*Please see attached file.

BOOSTXL-DRV8305EVM_output wave form.xlsx

I am considering about CH7 and CH8 wave form.

If you need some condition of this experiment, please inform me.

Best regards,

    Hi,

    Current on ch7 and ch8 looks fine. This is ringing effect in response to excessive HF gain.

    In this case, amplifier is amplifying the harmonics (rising/falling edges) present in the input signals in such an extent, its peaks are overshooting and start oscillating. I think this is the reason of ringing effect on captured current waveform.
