Part Number: DRV8301-69M-KIT
Other Parts Discussed in Thread: DRV8301, MOTORWARE

Regarding the hardware of the DRV8301 kit,

DRV8301 evaluation kit consist of 6 power mosfets, If we increase the number of power mosfets( for our design).

1. what are the precaution measurement we should look into and,

2. What are all the changes needed to be made regarding the software (i.e, in motorware).

Thanks,

Vivishekh

    You might refer to the datasheet of the MOSFET and the gate driver, or some textbook about electrical power circuit. I don't think you can increase the number of power MOSFETs directly on this EVM kit, you should design your board if you want to support a higher power output.

    From the software design side, you should set correct parameters based on the hardware board in user.h

    #define USER_IQ_FULL_SCALE_VOLTAGE_V           (24.0)

    #define USER_VOLTAGE_FILTER_POLE_Hz               (335.648)

    #define USER_ADC_FULL_SCALE_VOLTAGE_V       (66.32)

    #define USER_IQ_FULL_SCALE_CURRENT_A           (41.25)

    #define USER_ADC_FULL_SCALE_CURRENT_A       (82.5)
