Dear Sir,
I would like to generate low frequency PWM using ePWM module. I use F28377D to generate it in simulink as [1].
I try to generate 50 hz frequency using prescaller divider as shown [2], the detail implementation purposed in simulation of as shown in [3].Also the ePWM setting as in [4]
"however, there is no output in ePWM pinout"
Could you please to assist me pelase ?

Hello Arifin,
I understand that you want to generate low frequency PWM for ePWM module for F28377D launch pad and not able to see any output at the ePWM output pin.
Here is a MATLAB example on 'generate ePWM Waveform for Specified Frequency and Duty Cycle':
This will help you in generating the PWM for your launchpad.
You can also have a look at the example using the command below:
openExample('c2b/UsingEPWMExample')
Hope this helps!
