Hi E2E Community,
Currently I am setting up EPWM sub-module to output two PWM output signals to drive a half bridge inverter. These two PWM signals (EPWMxA and EPWMxB) are interleaved with 180 degree phase delay. In the past, we used external logic circuit to prevent the PWM outputs overlapping (If EPWMxA and EPWMxB are both high, it will cause shoot-through in the inverter bridge). The Dead_band sub-module seems to work with complementary PWM signals to prevent overlapping, but not with interleaved PWM signals (Please correct me if I am wrong).
My question is here: Is the trip-zone logic able to prevent the two PWM signals overlapping in interleaved PWM signals?
Thanks for your support,
Qinghua
