I would like to ask which register sets the modulation amplitude of the sine wave

thank you

Simply put, there is no such register. I need more information about your system to help you. Are you using a specific example? Are you bit-banging a GPIO or using an ePWM module?

I am using ePWM modules. I want to use the three phase inverter to vary the speed of an induction motor. to influence both the frequency and voltage magnitude

Have you looked at any of the example code available in ControlSUITE? I would suggest that you start there to get an idea of how a C2000 motor control example implements control using ePWM for ACI motors

There is a good document here to help you get started: C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVACI_Sensorless\~Docs

If there are no more questions here, I will close this thread for now
