Please advise a method to lower the ripple of the output electric current with DER-528 board..
Based on the DER-528 document, the current regulation is at 2.8% at most. For better regulation, you can try to tweak the RC values of C12 and R18 or you can refer to the Application Note provided below to further improve current regulation.
You're very kind.
After measuring DER-528 board; the mean of the output electric current is 359mA. The change width of the electric current was 336mA.
So I asked it. Thank you for advice.
