Question

I want to explore and test my PWM singles and how a 3 phase inverter works so need below requirements

I am looking for a motor driver / evaluation board recommendation.
My application requires a 3-phase inverter stage for driving a BLDC/PMSM motor.
Key requirements are:

  • Input Voltage: 20 V – 30 V DC (nominal 24 V system)

  • Power Stage: 6 separately controllable MOSFETs (3-phase inverter)

  • Control Interface: I want individual gate control for each MOSFET (I will generate my own PWM/FOC control signals).

  • Load: BLDC / PMSM motor

  • Current Rating: Medium power (please suggest boards with scalable current capability)

I am not looking for an integrated driver IC performing FOC internally — I specifically need access to each gate input so that I can run my own motor control algorithm.

If ST has any evaluation boards, power stages, or MOSFET gate driver boards that match this requirement, please recommend model numbers or links.

Thanks!
