Novel coupled-inductor multiphase vrs

WebIn this thesis, coupled inductors have been applied to multiphase DC-DC converters. Detailed analysis has been done to investigate the benefits of directly coupled inductors and inversely coupled inductors, compared to conventional uncoupled inductors. In general, coupled inductors for multiphase DC-DC converters have inherent benefits such Webfaster transient performance. To improve above issues in today’s multiphase non-coupled VRs, inversely coupled inductor VRs are proposed mainly to im-prove transient response significantly so that both real estate and cost could be saved on output decoupling [1] [2]. Some studies also shows that inversely
