Good Morning:
For problem 2 (input filter), a value of D = 0.36 is given. On the schematic given in Figure 1,
there are no feedback control loop elements shown except for Vc and VM. Are the other feedback elements assumed to be in the circuit and not pictured in Figure 1?
Does this mean that we are to simulate the sync-buck converter with input filter in "open-loop" form?
I understand that in order to get the transfer functions requested, we will have to use the averaged model (uncheck the "switching model?") box. This would lead one to believe that the given information of D = 0.36 is irrelevant to the questions being asked.
Thanks,
Alex
There is no feedback in this problem - you work with open-loop converter. But, D=0.36 is very much relevant here, as this steady-state duty-cycle value sets the operating point of the converter.
