Hi all,
I want to implement HVPSFB to my F28035 Piccolo. In this evaluation kit, F28027 is used but I think there is not much difference between those two. My main problem is that, while one MOSFET is turned off when the comparator output goes high, the complementary MOSFET is turned on with some dead-time. I mean it is written as in User's Guide_v1.1 "Whenever the comparator output goes high in a PWM half cycle, the ePWM2 module output (ePWM2A or ePWM2B) which was high at that instant is immediately pulled low while the other PWM2 module output is pulled high after an appropriate dead-band window (dbAtoP)."
In datasheet and some other forum posts, it's written as dead-band module cannot be used while tripping with digital compare events such as comparator output event. I looked at the pwm configurations very carefully and didn't think it's done in pwm configurations. Maybe it's configured in the ISR but I am not familiar with the assembly. Therefore I could figure out how it could be possible.
If someone help me about it, I would be very appreciated,
Thank you in advanced.
Steve
