Abstract :
This paper presents a buck-boost converter controlled by periodic inputs and provides the basic theoretical results, As an efficient analysis tool, we derive a slope chart that displays the relationship between slopes of the return map and those of the inputs. Applying the tool for the case of triangular inputs, we can give a sufficient condition for chaos generation. We then give a method to realize uniform distribution of the chaotic switching time intervals for any DC output: it might be a criterion to improve EMC. A method to realize super stable periodic behavior is also given
