Abstract
This paper presents an analysis of characteristics of multiphase buck converters with coupled inductors. We derive equivalent inductances that provide both low per-phase steady-state ripple current and fast transient response. The characteristics of coupled-inductor circuits - low per-phase ripple current and fast response - were examined and verified by circuit simulation and experiments.
