Query: A Closed-loop controller to improve the Stability of Cascaded DC/DC
  Converters   Study of the buck converter and cascaded system considering the voltage mode
controller has been done. First the small signal analysis of a buck dc/dc
converter is presented and its mathematical representation has been showed.
Then, the cascaded converter model regarding close loop impedances and voltage
gain has been studied. The controller for this converter is proposed to
stabilize the performance of the plant. The effectiveness of the proposed
controller has been tested on a typical buck converter.
