Controlling chaos in buck converters
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003A dc-dc buck converter controlled by naturally sampled, constant-frequency pulse width modulation in continuous conduction mode gives rise to a great variety of behaviors, depending on the values of the parameters of the circuit. This paper reexamines the buck converter studied by Fossas and Olivar [1996] and analyzes a method of controlling chaos ...

Digitally controlled buck converter
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004Digitally controlled step down converter with different control law algorithms is studied in this paper. The state controller is designed to eliminate the start-up overshoot and reduce maximal dynamic error of load change response, but the state controller is not capable of eliminating the steady-state error under the load change condition. By using an
