DRV8329-Q1: Adding Three-Shunt Current Sensing to DRV8329A for FOC Control

Tool/software:

Hello,

I am using the DRV8329A inverter board, which supports single-shunt current sensing. However, for better precision in FOC (Field-Oriented Control), I would like to implement three-shunt current sensing.

Is it possible to modify the DRV8329A circuit to support three-shunt current sensing? If so, what modifications or external circuits would be required to achieve this? Additionally, how would the current feedback signals be interfaced with the controller for accurate current measurements?

Any guidance on hardware modifications and firmware changes would be greatly appreciated.

Thanks in advance!
