Hi,

I'm having problems when I enable the option IMMEDIATE CMP Reg Load On ePWM block. Attached are figures with example of where I'm doing and the block configuration ePWM.

In PWM output pin put an RC filter to reproduce the sinusoid. However, there pulses do not know where that's going, like failures when comparing sine and triangular waves, for example. The attached figure show the result of the sinusoidal and triangular waves PWM and reproduced.

I would appreciate your help to fix this. Urgent need of results, because I have to finish the project report.

Thank you.
