In this paper, analysis of a buck converter operated applying a peak limiting current mode control is performed, focusing regions where the limit cycle is unstable. Normalized discrete time converter model is derived. Chart of operating modes is presented, and it is shown that the converter exhibits an infinite number of discontinuous conduction modes in an area where the continuous conduction mode would be expected assuming stable limit cycle. The converter is analyzed applying numerical techniques to determine period number of different discontinuous conduction modes and dependence of the output current on the output voltage and the limiting current. The numerical results agree with the analytical results in areas where the limit cycle is stable, and differ in regions where the limit cycle is unstable. Two different notions of stability, the limit cycle stability and the converter open loop stability, are clarified.
