Analysis of Limit Cycles in a PI Digitally Controlled Buck Converter

Bradley, Mark ; Alarcon, E. ; Feely, Orla (IEEE, 2012-05-20)

Digital control of power converters has been an area of considerable research interest in recent times. One of the problems which arises in these systems is that of the limit cycle oscillations that occur due to quantization ...
Limit cycles in a digitally controlled buck converter

Bradley, Mark ; Feely, Orla ; Teplinsky, Alexey (IEEE, 2011-08-29)

We describe the mathematical model of a digitally controlled buck converter. This model is an autonomous discrete-time discontinuous piecewise-linear dynamical system in three dimensions. Investigating this system, we ...
