How does the TI C2000 ePWM block work?

I am presently attempting to generate ePWM pulses for a model that will be deployed onto a TI C2000 board.

I noticed that the ePWM block seems to be designed for this purpose, but I am having trouble understanding how to use it.

Would you be able to explain how this block works?

Essentially, each ePWM block configures how a particular ePWM module on the F28379D board fires the ePWM signals.

Under Model Configuration Parameters -> Hardware Implementation -> Target hardware resources -> ePWM, you are able to specify which GPIO pin each PWM signal maps to.

I have attached an example of how this block would work, along with an image that provides a high-level overview of the configuration process.

Below is a link with more information about the capabilities of the ePWM block:

@MathWorks Support Team here u meant can use GPIO together with ePWM in same model?

i do not understand what did you mean of (to specify which GPIO pin each PWM signal maps to)

i have inverter implemented it by GPIO using normal pwm but I want to use SPWM pulses so I should use ePWM block and need to know how to start.

this ur example but do not understand

Hi Mathworks support,

I am trying to figure out my inverter model by ePWM signal in TI c2000 using Simulink. Can you guys please help me out.

my inverter like full bridge and want to implement it my hardware matlab using a library of F28379D
