| Abstract |
This paper will present the procedure of small-signal
modeling of a peak-current-mode controlled Forward
converter in continuous inductor-current mode. The effect
of transformer isolation on the dynamic performance is of
special interest. It has been noticed in practice that the
transformer isolation has significant effect on the dynamic
behavior but is not fully understood or modeled earlier.
This effect can be modeled in a similar manner as the effect
of artificial compensation ramp but adding also the
dynamics of input voltage. This will change significantly the
duty-cycle constraints and consequently the dynamic
behavior. |
