| Abstract: | To eliminate the four-phase voltage regulator modules(VRM) of the DC bias and improve the dynamic response speed,the combination method of "field" and "road" was proposed.The principle of integrated magnetics to eliminate DC bias was elaborated,and part of the integrated magnetics had the thin-film design.The circuit simulation and the finite element simulation show that the DC bias of integrated magnetics is eliminated,and the dynamic response of interleaved converter is improved. |
