LAUNCHXL-F28379D: No ePWM output with reference to ADC sine wave input while using Launchxl-F28379D
I am trying to generate PWM pulses for my full bridge inverter from Launchxl-F28379D by using Embedded Coder Support Package for Texas Instruments C2000 Processors. The reference for the PWM pulses are given to the Launchxl-F28379D through the ADC input pin.
Specification of input reference wave - Sine wave (0-3 V pk-pk, freuency varying from 10 kHz to 25kHz).
When I tested the model, there were no PWM pulses generated from the ePWM module. After that I tested the model using monitor and tune option. The ADC output was observed through the scope and it was not same as the input sine wave. It was highly distorted and it was not following the input frequency. What may be the possible reason for this ?
Is it possibe to generate ePWM with reference to a Sine wave with (0-3 V pk-pk, freuency varying from 10 kHz to 25kHz) ?
What are the settings that should be considered while doing this experiment ?
How do I select sample time in ADC block ?
Please ask if any other details regarding this is needed.
