Abstract
Applying feedback control to a flyback converter in discontinuous conduction mode causes instability by a jump phenomenon under some snubber circuit conditions. In this paper, we clarify this jump phenomenon, analyze stability, and discuss circuit constants to avoid this jump phenomenon. We propose current-mode control without relying on circuit constants
