TIDA-010062: Question about closed loop current

Hi Green,

Do you mean, customer is running 'Lab3' close voltage loop, and the ac input current is out of control, then triggerred OCP fault?

Hi Desheng:

Customer is running "lab4", and commissioning without overcurrent protection.

Otherwise, under the condition that no protection is turned on, the output voltage is greatly different from the reference output 380V. Will there be any impact in closed loop?

I am confused.

What is your problem? current too large, or output voltage is different?

Hi Desheng:

Customer reported 2 questions:

When running in no-load condition, the open-loop current is normal, but the close-loop current is too large.
