Low THD

Posted by: aliaykan on

Hi,

How can I reduce the THD below 10% in all load range with PFS series PFC? Is it directly related with KP ratio?

 

Best regards,

inductor has big impact on THD. You can try a larger inductor. Also you can add heavier EMI filter components, for example larger DM choke has great impact on THD as well.
