TIDM-SOLAR-ONEPHINV: EVM Code x Solar lib

teves voador

Hello All,

We are developing a solar inverter using EVMs : http://www.ti.com/tool/TMDSHVMPPTKIT and http://www.ti.com/tool/TIDM-SOLAR-ONEPHINV.

We've realized new EVMs:

HV_1PH_DCAC - http://www.ti.com/tool/tidm-hv-1ph-dcac

TMDSSOLARUINVKIT - http://www.ti.com/tool/TMDSSOLARUINVKIT

TMDSSOLARPEXPKIT - http://www.ti.com/tool/TMDSSOLARPEXPKIT

Comparing software implementation we realize the new EVMs are using Solar Lib in ISR blocks. However, in TIDM-SOLAR-ONEPHINV (the EVM that we have)

there are several blocks to do control of the output current, DC voltage bus and grid voltage phase.

Are the solar lib ISR blocks more eficient than the code in TIDM-SOLAR-ONEPHINV? Both works fine?

Thanks,

Regards

Teves,

The ISR based C code approach in the new EVMs is more scalable and maintainable. this will be approach going forward as well.

from a functionality perspective, both are the same.

Hi Manish,

Thanks for your explanation.

- Could we make a change and use the SolarLib SPLL block, for example, in the TIDM-SOLAR-ONEPHINV? Is it possible?
What is your opinion about this change?

- Which controller of C2000 family would you advise to use for a 3 kW comercial single phase string inverter with MPPT?

Regards,

Hi Manish,

Could you please take a look at the other questions I posted?
