C2000 micro inverter questions

Hi Craig,

1. My board is rev 4 but the schematic in controlsuite is rev 1.0. do these match?

Yes, you've to refer v1.0 and you can the schematics here:

C:\ti\controlSUITE\development_kits\TMDSSOLARUINVKIT_v100\HWDevPkg

2. T2 is listed as VITEC   58PR6962    TFMR Flyback, ViTEC 58PR6962. I called Vitec for datasheet, they said its a custom part and to call TI for datasheet. Who should I call to obtain this?

If you check the following link:  http://www.viteccorp.com/index.php?categoryid=41

The ViTEC 58PR6962 does not seem to be a custom one. Also, you'll have to call or mail ViTEC guys for more info as its not TI's custom made product.

Guatam,

I called vitec before I posted my questions here. They said to call TI for more information. Should I call and ask them again?

Thanks for replying.

Hi,

I search that datasheet too, have you found her since your last post.

Thanks

Did you get any update from the vitec guys? Do update us.

I've also reached out to Vitec, to no avail.  I'm not interested in the VITEC 58PR6962 in specific, I mainly would like to know general specifications of the transformer.

Namely, turns ratio, primary/secondary inductance, rated power handling, recommended frequency operation/resonant frequency information, etc...  I want to peer check my design against the basic specs to see if I'm in the right zip code.

As Vitec has not been helpful with our requests, I would assume someone at TI has, if not the data sheet, at least some general knowledge of this transformer.  

Another way of asking the question would be:

On your C2000 Piccolo based Solar Micro Inverter (TMDSOLARUINVKIT), what are the general specifications of the DC to DC flyback transformer?  Namely turns ratio, and primary/secondary inductance?

Any information would be greatly appreciated,

Regards,

Peter

Peter,

I am working with the part manufacturer to see what we can provide.

Will post back when i have an update

Glad to find the 58PR105' datasheet ,but I am not sure what is the value of 58PR105 used in  TMDSSOLARUINVKIT.Is it 7200uH , 1680uH or 420 uH?

The flyback transformer has only one value , please see the spec Flyback_TFMR_ViTEC_58PR6962_072213.pdf attached in the previous post.

The inverter inductor is 53PR105-722 with a min inductance ~5mH

Hi,there is something wrong of the 58pr6962 in my c2000 micro inverter after my improper operation by accident.So I just wanna to buy a 58PR6962 to replace it. I have tried many ways but no one sell it with only one or several quantities. Could you tell me whether Ti sells it  or where we can buy,please?
