Abstract
Applying feedback control to a flyback converter in discontinuous cond uction mode causes instability by virtue of a jump phenomenon under so me snubber circuit conditions. In this paper, we clarify this jump phe nomenon, analyze stability, and discuss circuit constants to avoid the phenomenon. We propose current-mode control without relying on circui t constants.
