Hi Team,
The customer uses the AMC1306M25 to capture the phase current of the motor and the SIN3 filter generated by the FPGA to capture the data.
If the SINC3 filter is in continuous operation, the data sampling is as expected. However, if a brushed SINC3 filter is used, the data obtained after three acquisitions is smaller than the actual value. Through modelsim simulation it can be found that the data was correct after four samples and that the data was small for three samples.
However, according to many resources, three samples will yield stable data.
Could you help check why's this? Thank you.
Best Regards,
Cherry
