TMS320F280049: How to implement auto current limitting with Epwm in BLDC motor driver?

Part Number:TMS320F280049

Support Path: /Product/Development and troubleshooting/

Hi all,

I am going to implement a BLDC motor driver board with F280049 (and DRV8320RH), and I hope to add an over-current-detecting function to it, so that when the voltage is unstable the motor can keep running smoothly.

So far I notice that there is a "Peak Current Mode" from the ePWM chapter of device manual(SPRUI33A), which making ePWM module to work with the internal comparator to realize extra compensation for 3-phases PWM outputs.

But only the application about DC-DC converter is demonstrated, so I am wondering if this "Peak Current Mode" featrue can also be used for cunrrent limitting purpose. If not, is there any other way to do that?

Any help is appreciated.
