For a complementary EPWM1 output to drive a half-bridge IGBT/SiC module, I will be using the "activehigh complementarty dead-bead mode" with equal RED and FED.
EPWM1 is operated in the up-down count mode.
If RED/FED is greater than the original pulse width (i.e. before a deadband is implemented), what will be the actual outputs at the processor pins?
This question is arising since with my SVPWM at certain modulation indices, I could get some original pulses (i.e. before a deadband is implemented)
with pulse widths less than or equal to RED/FED.
Thanks

The deadband module should block everything out on your original PWM if the pulse width is low. I dont think it should cause an issue.
