Abstract :
The stability analysis of a buck regulator with DC and AC feedback loops has been investigated theoretically for the continuous conduction mode by applying the z-transform method. The analysis has been extended to the discontinuous conduction mode by means of an analogue computer simulation. These last results have been verified successfully on an existing breadboard. It appears that the introduction of the AC loop allows fast transients independent of the output filter parameters and improves the overall stability of the single loop regulator.
