"Plot (by hand) magnitude and phase Bode plots of the loop gain T for the two extreme load current values, and determine the cross over frequency fc and the phase margin in both cases. "
I assume that this is the loop gain for the entire feedback loop and not just the compensator. Is this the assumption others have made as well?
Yes the entire feedback else there will be no effect from the load current change.
ReplyDeleteNote that Gvd is dependent on operating point. Thus R dependent. T should be different for the two cases
