TIDA-010039: Operational Questions

Part Number: TIDA-010039

Hey Team,

Is the TIDA-010039 bidirectional? I see that in the main description of the reference design, that it states bidirectional functionality, but then goes on to say " For design information on the DC/AC implimentation, see TIDA-01606." What should I be looking for to achieve this type of functionality?

If the TIDA-010039 is bi-directional, does it need to be grid-tied when acting as an inverter? Is there a way to tell if one of our designs needs to be grid-tied for operation? I am wondering the same thing for the TIDA-01604.

Thanks,
Dajon McGill

    Hi Dajon,

    Yes, TIDA-010039 is bidirectional.

    1606 and 10039 use the same hardware

    10039 shows the mode of operation as PFC (AC to DC conversion)

    01606 shows the mode of operation as Inverter (DC to AC conversion)

    I do not know much about the capabilities of TIDA-01604, but as far as 01606 is concerned, it can be run as an inverter just tied to the resistive load. (Lab 3 of the code demonstrates this feature). Lab 4 will be the mode where grid tied mode is used where in the ac side of the inverter is directly connected to grid.

    Please let me know if you require any clarifications.

    Thank you

    Harish,

    When acting an an inverter (DC to AC), does the TIDA-010039 need to be grid-tied?

    Can this Lab 3 code be used on the TIDA-010039?

    Additionally, where is this Lab 3 code?

    Best,

    Hi Dajon,

    Yes , Lab 3 code can be used in TIDA-010039 to operate it as inverter. To verify this mode connect resistors on the AC side. To verify grid tied mode on TIDA-010039 use Lab 4 code. Note: We have not tested the grid tied mode (LAB-4) in actual hardware only lab-3 has been tested. Please let me know if you have any questions.

    Regards,

    Hi Harish,

    I still cannot find Lab 3. Can you please provide a link?

    We want to use Lab 3 code with the TIDA-010039 to operate as a standalone (not grid-tied) converter. We want to tap a 120VAC and 240VAC output from it. On this topic, I have a couple questions:

    Can it run single phase out?

    Can we tap three separate single phases off of it?

    Best,

    Hi Dajon,

      Yes, you can tap 120Vac (L-N) /208Vac (L-L)

     

    Please see the diagram below:

     

     

    I have not tested it at 240Vac, but we have verified at 230Vac for 800V DC input at inverter terminals. We have never tapped a single phase from this three phase converter to run single phase loads. Theoretically it should be possible to run but we have not checked it in our lab.

     

    Thank you

     

    Regards,

    Harish
