I have been looking through the famous app note on Average Current Mode Control by L. Dixon,https://e2echina.ti.com/cfs-file/__...-Mode-Control-of-Switching-Power-Supplies.pdf.
He gives many examples on how to use current mode control for input/output current and for flyback topology. I am quite novice when it comes to control theory, so I was wondering - is it possible to use average current control on the secondary side of an isolated DC/DC converter, such that we control what is essentially a "DC" current (with small ripple). My converter is a buck converter that is cascaded into a half bridge resonant converter, and controlling the buck output inductor current does not seem to be sufficient in regulating the converter under transient conditions. I thought maybe I could try controlling the secondary current and modulate the buck converter according to this for tighter control.
So, is it possible? Is it recommended?
