TIDM-1007: AC drop testing

Wayne Huang

Part Number: TIDM-1007

Dear Champs,

I am asking this for our customer.

Have you done any AC drop testing on TIDM-1007?

Our customer is concerned if AC drops for a short time and then recovers, can our design still work smoothly and correctly for that?

Or do we have any code to deal with this situation?

Do you have any comment?

    Hi Wayne,

    We did not conduct any AC drop tests for the released TI design. Thanks.

    Regards,

    Chen,

    The customer said TP PFC is more susceptible to AC drop/recover noise than traditional boost-based PFC.

    As we did not do any AC drop test, we would like to know:

    1) Our algorithm in the control loop should be strong enough for AC drop testing?

    2) or we do not implement any for AC drop testing?

    If so, should we have any suggestion for customers to implement it?

    Say in the current/voltage control loop or in background codes?

    Hi Wayne,

    For TIDM-1007, we do not implement any for AC drop testing so we don't have much input in terms of the specific implementation. However, It will be put into the current and/or voltage loop since the algorithm might need to be implemented to modify the voltage/current command during the AC drop period. Thanks.
