How to configure the switching frequency using ePWM block?
First I've set the ePWMLink TBPRD to ePWM1 and got the switching frequency as 2kHz
Then changed ePWMLink TBPRD to Not Link and set Timer Period as 60000 ( By calculation Fpwm = Fclk / (2* TBPRD), decided Fpwm as 10kHz)
In both the cases I'm getting Switching frequency as 2kHz. How ePWMLink TBPRD works and how can I get the desired Switching frequency?
And also how to configure ePWMA and ePWMB?

Hello Abirami,
I understand that you are trying to achieve desired switching frequency using TI C2000 ePWM block in Simulink.
In order to configure the switching frequency of ePWM block, first we need to consider the counting mode depending on the application.
The TBPRD calculation for a switching frequency of 10KHz is as shown below for both the counting modes.
You can also refer to the “ePWMA and ePWMB” section of the documentation Generate enhanced Pulse Width Modulated (ePWM) waveforms - Simulink (mathworks.com) for more information regarding ePWM block.
Thank you.
