TMDSSOLARPEXPKIT

Prasanna Piya

We have recently bought a TMDSSOLARPEXPKIT kit with F28035 control card. We want to test our inverter control algorithms. Can we use only the inverter of this kit neglecting mppt, dc-dc converters and pv emulators?

Can we use F28069 card with this kit. (We programmed the F28069 card with code available in control suite for solar inverter with F28035 card but it didn't worked as intended.)

We also want to know the value of L and C of LC filter used in this kit and also the switching frequency of the inverter.

Thanks.

Hi, (Thanks IGOR)

Please check for the GPIO compatibility of both the controllers. Some modifications have to be done to convert the F28035 code to F28069.

Note: The sample codes available for F28035 controller are not compatible with F28069. So you'll have to modify the whole code according to F28069.

Hello Gautam!

F28069 has FPU! 6787.TI_TMS320f2806x_overview.pdf.

Igor, how big difference does the FPU to the code?

Is it possible to run IQ math code in F28069 with IQmath.lib / or is a must to use IQmath_fpu32.lib?

Why I'm wondering is that I have manage to modify the exampel code for PV Emulator which is coded for F28027 in Solar Explorer kit to compile and execute on F28069.
Thing is that I haven't got the assembler code to working on the F28069 yet.

Hi Daniel,

You can make use of IQMath lib for F28069; no issues.

Hi Daniel!

It is possible. This question is discussed in details within this thread http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/281731/984298.aspx#984298.

Hi Igor and Gautam!

Yeah, I managed to figure it out that it was possible by using IQmath_fpu32.lib almost right after I posted.

Thanks any way!
