I am using a triggered sub-system in Simulink with ADC triggered. I need to generate however two different switching frequency for my dc-dc converter and the H -bridge inverter. How can I do that inside the triggered sub-system?

Hi,

So you want to change the switching frequency for the given ePWM module from A Hz to B Hz based on a condition?

Could you please elaborate more on the requirement or the design.

No two different switching frequency will be continuously generated. for two different conveter.

Hi,

Please refer one of our shipping example: 'c28379Dpmsmfocdual_cpu1_ert'

Here we have 2 triggered subsystems. You need to do the same in your case.

Have a C28x HW interrupt block and configure 2 interrupts for each instance of switching frequency.
