I am working on a new converter design, and for the topology in question, I was looking to use triangle modulation to take advantage of average inductor current sampling. For the converter topology, I'm using duty cycle control, and I was hoping to use the HRPWM function to control both the rising and falling edges. The technical reference manual states that this functionality is really only meant for phase shift modulation, but is it possible to control both the rising and falling edges with the HRPWM output using the CMPAHR/CMPBHR registers?
The allowable duty cycle will be limited to avoid the MEP limitations near the zero and period transitions. It just wasn't clear if the ePWM module would work as expected, or if I am stuck only having high resolution on a single edge. Any help would be appreciated so I can plan to configure the PWM accordingly. Otherwise I will need to take additional steps for implementing current mode control in this converter.
Best regards,
Lance
