Part Number: TMS320F28335
Other Parts Discussed in Thread: TIDA-01606, , TMDSDOCK28379D, C2000WARE, C2000WARE-DIGITALPOWER-SDK

Dear Sir, need help to implement 2P2Z controller for dc voltage on TMS320f28335 DSP for three phase grid connected inverter. Please suggest if there is any reference design available. I am not very much conversant with MATLAB.

Also I have Implemented 3phase SPLL and getting theta. If I construct sine wave using that theta it get synchronized but if I reconstruct after find d-q components it gives 30 degree phase shift as SPLL gets input with respect to neutral . Please guide me to understand this issue.

Thanks for your help.

Manish,

We can try to help you on specific items on the collateral we provide. We cannot debug your system.

All our maintained collateral is on newer devices for system solutions, F28337x f28004x

Typically you may observe an offset depending on type of transform used. We have a design TIDA-01606 and we do have some SW available for it that might help you. in case you are interested in working with F28377x i can share the link with you to request the SW.

Dear Manish,

Thank you for your reply. As I am having target board for TMS320F28335 I thought to start the work with the same. But no problem if I have to shift F28337x.

I will order kit for that and will shift to F28337X. Meanwhile request you to suggest me how to implement 2P2Z controller for DC voltage Control.

Regards

Manish

Dear Manish,

Please also suggest control board for TMS320F28377x. Can we use TMDSDOCK28379D ?

Manish,

Yes the docking station will work nicely for this.

For 2p2z we have a collection of libraries in our DCL library, they come in the C2000ware package,

I will highly recommend you to install C2000Ware-DigitalPower-SDK

C:\ti\c2000\C2000Ware_DigitalPower_SDK_3_00_00_01\c2000ware\libraries\control\DCL

we have all examples of systems using DCL library,

Thank you Manish. Will TMDSOCK28379D F28379D Delfino Experimenter kit will do the job?
