Bifurcation analysis of a power-factor-correction boost converter: uncovering fast-scale instability
Faculty of Computing, Health and Science
School of Engineering
Bifurcation analysis is performed to a power-factor-correction (PFC) boost converter to examine the fast-scale instability problem. Computer simulations and analysis reveal the possibility of period-doubling for some intervals within the line cycle. The results allow convenient prediction of stability boundaries. Analytical equations and design curves are given to facilitate the selection of parameter values to guarantee stable operation.
