Aiming at normal PWM low efficiency at light loads
the author proposed a novel high efficiency modulation mode named pulse skip modulation mode PSM.This paper establishes the large signal model of the novel PSM switching converter mode
which includes large analytical model
discrete model and phase plane model.Basing on its analytical model
discrete model and phase portrait
the transient characteristics of the open and closed PSM converter are given in this paper.Compared with PWM converter
PSM converter has quicker response and better interference rejection besides high efficiency.
