Hi.
I designed the motor driver using the IC controller IMC102 and switch IFCM15P60GD for the motor PMSM with Power 750W, and in practical testing, the network input parameters are THD current about 11%,
but I want to reduce it below 5%.
What solution do you suggest for me?
What parameters should I change in MCEWizard for controller PFC?
How do I tune the parameters PFC in MCEWizard & MCEDesigner?
thanks

Hi,
PFC tuning for lower THD is dependent on current loop tracking performance and voltage loop ripple attenuation.
For the current loop, both Ki and Kp need to be adjusted reasonably to increase integral gain while keeping it stable. The duty-feed-forward factor might also need to be adjusted here.
Best regards,
Hari
