Hi,experts
This is PWM and CBC-OCP, designed for Totempole bridgeless PFC.
Here, I need to use two PWM for one half bridge, and the two PWMs are compensate with each other. ( If PWM1 is low, PWM2 is high; if PWM2 is low, PWM2 is high. And, there should be deadtime both are low)
When I using the tripzone to do the CBC OCP protection, I need to trip PWM1 low@'positive AC line cycle', and trip PWM2 low @ 'negative AC line cycle'.
But, when the trip happens, I sametime need to the compensated PWM channel. That means when PWM1 is triped to low, PWM2 should be forced to high with a deadtime.
Could I use a same tripzone to trigger PWM1 low and PWM2 high in 'positive AC line cycle', and reverse the action (trigger PWM2 low, and PWM1 high) in 'negative AC line cycle'?
How to do that?
