Hi,
Q1: I don't understand why Dmax is derived at fmax? From below formula, the duty cycle is minimum when switch frequency is maximum, isn't it?
:
Q2: I don't understand the principle why Dmagcc is fixed internally at 0.432, it is the secondary winding conduction radio Td/Ts right? How to make it a fixed value at CC mode? Can you share a CC model control block diagram to understand.
Q3, My design will works at CV mode, rather than CC mode, how to set it works in CV mode rather than CC mode?
