Greetings
Recently I'm working on some coding work related to selective harmonic elimination for single phase inverter.
Comparing with traditional constant frequency PWM, SHE is different.
In constant frequency PWM, the period is constant but only duty cycle changes so that it is easy to configure the ePWM module.
In SHE, the duty cycle and period both changes so that it is kind of tricky to program things like this. I wonder whether it is feasible to use interrupt and configure the duty cycle and period at the same time?
One direct way for doing this is to use timer and toggle GPIO output. However, I'm worring about the deadband settings in this way.
If you have any suggestions, please share me your ideas!
Thanks !!
