Generate Low Frequency using ePWM module

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 ?

I hope MATLAB staff can answer this question and give a solution~

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':

Generate ePWM Waveform for Specified Frequency and Duty Cycle - MATLAB & Simulink - MathWorks India

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!
