This study presents a detailed investigation on bifurcation of general period-1 behaviour in a pulse width modulation (PWM) controlled dc series motor drive system. Existence of quasi-periodic behaviour and different bifurcation routes are mainly explored for the drive system under voltage mode control. Occurrences of different types of bifurcations are also validated by computing Floquet multipliers...
Due to features of near-unity power factor, soft turn-off switching and low switch current stress, Cuk power factor correction (PFC) converter operating in discontinuous capacitor voltage mode (DCVM) has attracted much attention. However, it is found that with the increase of intermediate capacitance, slow-scale instability occurs in voltage mode control (VMC) DCVM Cuk PFC converter. In this study,...
