TIDA-010210: Inquiry about reference designs

Part Number: TIDA-010210

Hello,

We have received an inquiry for the development of a 95 kW solar string inverter and are currently evaluating suitable control and power-stage solutions.

Could you please let us know if TI has any reference designs, application notes, hardware platforms, software libraries, or design guides available for solar string inverters in the 95 kW power range? We would particularly be interested in information related to:

  • MPPT control implementation
  • Three-phase grid-tied inverter control
  • T-Type/TNPC inverter topologies
  • C2000-based solutions
  • SiC gate driver solutions
  • Grid synchronization and protection functions
  • Relevant reference designs or evaluation boards

Any available documentation or recommendations would be greatly appreciated.

Thank you for your support. We look forward to your response.

Best regards,
Apurva Agre

    Hi Apurva, 

    Thanks for your question. 

    So for three-phase designs in general, I can recommend looking into the following reference designs on ti.com:
    1. TIDA-010957 reference design | TI.com
    2. TIDA-01606 reference design | TI.com
    3    . TIDA-010210 reference design | TI.com

    For reaching power levels as high as 95kW, I see it as having a modular approach in the sense of having stacks of the converters together. 

    All the above mentioned designs have the software available online in C2000WARE-DIGITALPOWER-SDK Software development kit (SDK) | TI.com which implements certain labs with grid synchronization functionality, grid-tied inverter control etc. For MPPT control, various header files with MPPT implementations exist in the DPSDK as well which can serve as a good starting point: solar. 

    These reference designs are online on ti.com with corresponding schematics, BOM files, Altium database, Gerbers etc, so it can serve as a starting point for anyone developing their hardware and evaluating the systems. The design guide provides an insight into the design theory, calculations, component selection, test results etc. 

    Hope this answers your question. 

    Thanks,
