my.unimap-407472016-01-19T09:33:05Z Control of bifurcation behaviour of the buck converter via a resonant parametric perturbation circuit Chiang, Ng Kok Tien Tien, Michelle Tan Mei Lin, Nadia Tan kokchiang.ng@leonghing.com Link to publisher’s homepages at http://www.myiem.org.my/ Nonlinear circuits and systems research has been growing very quickly over the past two decades. Actively pursued in almost every branch of science and engineering, nonlinear systems theory has found wide applications in a variety of practical engineering problems. Engineers, scientists and mathematicians have similarly advanced from the passive role of simply analyzing, oridentifying chaos to their present, active involvement in controlling chaos – control directed not only at suppression, but also at exploiting its enormous potential. We now stand at the threshold of major advances in the control and synchronization of chaos for new applications across the range of engineering disciplines. All feedback controlled power converters exhibit certain non-linear phenomena over a speciic breadth of parameter values. Despite being commonly encountered by power electronics engineers, these non-linear phenomena are by and large not thoroughly understood by engineers. Such phenomena remaining somewhat mysterious and hardly ever been examined in a formal way. As the discipline of power electronics becomes more matured, demand for better functionality, dependability and performance of power electronics circuits will inevitably force researchers to engage themselves in more detailed study and analysis of non-linear phenomena and complex behaviour of power electronics converters. The bifurcation behaviour of the buck converter occurs when the input voltage is varied. In this study, the computer simulation scheme, PSPICE is employed to model the behaviour of the ideal buck converter. For certain values of the input voltage Vin instability occurs. The resonant parametric perturbation method is then applied to control the bifurcation behaviour of the voltage-mode controlled buck converter. Analysis and simulations are presented to provide theoretical and practical evidence for the proposed control method. As the buck converter has wide industrial application, it would be deemed necessary for designers to know about its bifurcation behaviour and how to control such behaviour. 2016-01-19T09:33:05Z 2016-01-19T09:33:05Z 2015-07 Other The Journal of the Institution of Engineers, Malaysia, vol. 76(1), 2015, pages 24-31 0126-513X http://dspace.unimap.edu.my:80/xmlui/handle/123456789/40747 en The Institution of Engineers, Malaysia (IEM) |
