Multi-period analysis of current-mode pulse-train controlled continuous conduction mode converter
View through CrossRef
Pulse train (PT) control technique is a discrete, nonlinear control technique for switching converter which benefits from simple design and ultra fast transient response. As an output-power-control-based control technique, a low-frequency oscillation phenomenon occurs in voltage-mode PT controlled switching converter operating in continuous conduction mode. This phenomenon will seriously affect the steady and transient performances of switching converter. In this paper, a current-mode PT (CM-PT) controlled switching converter is studied. The normally working region is studied and the parameter conditions are estimated. Targeting the problem of CM-PT control technique, a modified control technique is proposed.
