Because of the DC-bias in the magnetics of voltage regulation module(VRM), the size and loss can’t be reduced easily, this restricts VRM’s development of low voltage and large current and “light, thin and small”. In order to eliminate DC-bias, this paper proposed a 2-phase planar integrated magnetics and a 4-phase planar integrated magnetics whose DC-bias in the central poles and yokes can be eliminated in 4-phase interleaving VRM, and gave the theory analysis and the electric-magnetic design of the integrated magnetics with the method of combining “field” and “circuit”. The magnetics proposed in this paper have the advantages of shorter winding length, smaller winding area, smaller loss and simpler winding manufacture technology, and the core can be utilized most sufficiently. The simulation and experiment results show that the magnetics proposed in this paper are valid.
