Hi Champion,
I have a customer want to use PWM1A and PWM1B to drive a bridge, with complementary configuration. They want to use CBC trip to do the over current protection. However, when the over-current goes away. Next week,trip signal goes away,too. PWM1A is all right, but the EPWM1B is “cross period” since the couter mode(up-down mode), which means it will go on-and-off twice of chosen frequency, it will cause great switching loss on the MOSFET or IGBT. That is unacceptable. Could you give some suggestions to work around this?
