Multisampling of an ADC channel in a PWM cycle in TI C2000
Assuming your PWM above is ePWM1.
1 - Configure ePWM2 to be synchronized to ePWM1.
2 - Adjust ePWM2 period to be N times smaller.
3 - Now trigger the ADC sampling to ePWM2. Assuming you sample on the bottom and top of ePWM2 triangle, you will sample twice per ePWM2 period and 2*N times per ePWM1 period.
